Dual advantages of environmental protection and road surface protection

1. No chemical pollution, protect the ecological environment

• Traditional snow melting agents (such as sodium chloride and calcium chloride) can corrode road structures, bridge steel bars, and infiltrate soil and groundwater sources with water flow, causing vegetation damage and water pollution. And the heating cable converts electrical energy into thermal energy to melt snow, without the involvement of chemical substances throughout the process, avoiding pollution of soil, water and air.
• Case: After the use of heating cables in a certain elevated bridge, the pH value of the surrounding soil stabilized within the normal range of 6.5-7.2, while the pH value of the soil in the section using snow melting agent dropped to 4.8, showing a significant acidification trend.

2. Zero mechanical damage, extending road surface life

• Mechanical snow removal (shovel, snow sweeper) operations are prone to wear and tear on the anti-skid layer and markings of the road surface, and may even cause cracks in asphalt pavement or exposed cement pavement. The heating cable is buried under the road surface (usually 5-10cm away from the surface), and melts snow through internal heating without external intervention, completely avoiding physical damage.
• Data support: According to statistics from a municipal road, after using heating cables for 5 years, the cracking rate of the road surface decreased by 62% compared to mechanical snow removal sections, and the maintenance cost decreased by an average of 1.8 million yuan per year.

Intelligent automation and continuous snow melting capability

1. Dynamic response, decreasing and melting as needed

• The heating cable system can be equipped with temperature and humidity sensors, snow thickness sensors, and intelligent controllers to achieve unmanned operation of "automatic snow start and automatic snow stop". When the road surface temperature is detected to be below 0 ℃ and there is snow accumulation, the system can heat up to 5-10 ℃ within 10 minutes, melting snow while snowfall to avoid snow freezing.
• Application scenario: The mountainous roads in the Yanqing competition area of the Beijing Winter Olympics in China will use this technology to maintain a snow free surface during the continuous snowfall period in February 2022, ensuring the safe passage of racing vehicles.

2. 24-hour continuous operation, adapted to extreme weather conditions

• Mechanical snow removal is limited by manpower and equipment, making it difficult to cope with continuous snowfall (such as blizzards lasting for more than 12 hours), while heating cables can operate 24/7 without stopping midway. For example, after using heating cables on a highway in Altay, Xinjiang, the road remained smooth for three consecutive days of heavy snowfall (with a cumulative snowfall of 38mm) in the winter of 2023.

Adaptability to complex scenarios and precise temperature control

1. Targeted snow removal on special road sections

In areas prone to icing such as bridges, tunnel entrances and exits, steep slopes, bends, and pedestrian overpasses, heating cables can be flexibly laid according to the terrain to accurately control local temperatures. For example:

• Bridge scene: The bridge deck is more prone to icing due to the "heat island effect", and heating cables can maintain the temperature of the bridge deck at 2-5 ℃ to avoid ice formation (such as the application of Jinan Yellow River Bridge, which reduced winter traffic accidents by 75%);
• Pedestrian overpass: After laying heating cables on a university overpass, there were no sliding marks on the bridge deck during winter, and there were no incidents of pedestrians slipping.

2. Unrestricted by terrain, flexible construction

• Mechanical snow removal is difficult to operate in narrow sections (such as residential ramp, underground garage entrance and exit), while the heating cable can be bent (minimum bending radius ≥ 5 times the cable diameter) to adapt to various complex terrain, and can even be embedded under steps and tactile paving to achieve concealed snow removal.

Long term cost advantage and low maintenance requirements

1. The total lifecycle cost is lower than traditional solutions

• The service life of heating cables is usually over 30 years. Although the initial investment is high (about 200-500 yuan/m ²), the maintenance cost in the later stage is extremely low (average annual maintenance cost<5 yuan/m ²). Snow melting agents need to be continuously invested every year (about 10-20 yuan/m ²), and additional road repair costs need to be borne.
• Comparative data: According to calculations in an industrial park, the total cost (including initial investment and maintenance) of using heating cables for 10 years is 4.8 million yuan, which is 1.7 million yuan less than the snow melting agent solution (6.5 million yuan).

2. Low maintenance and no manual operation

• The system does not require frequent maintenance, only regular checks of the cable insulation layer and controller operation status, and the intelligent monitoring system can provide real-time warning of faults (such as leakage and overheating), making maintenance much easier than mechanical snow removal equipment (which requires regular maintenance of engines, hydraulic systems, etc.).

summarize

Heating cables form unique advantages in terms of environmental friendliness, intelligence, road protection, and long-term economy through the "electric melting snow" mode, especially suitable for key urban road sections, transportation hubs, and special terrain areas with high safety and environmental protection requirements. Although the initial investment is relatively high, its comprehensive benefits (reducing maintenance and improving traffic safety) far exceed traditional snow removal technologies, making it an important development direction for green snow removal in the future.

As a flexible heating material that converts electrical energy into thermal energy, heating film is widely applicable to a wide range of people due to its characteristics of uniform heating, flexible installation, and precise temperature control, especially in scenarios such as insulation, therapy, and special environmental needs. The following are the core applicable population classifications and specific scenarios:

People who are afraid of cold: those who have a strong need for daily warmth

• old people

The metabolism of elderly people slows down, blood circulation is weak, and they are prone to problems such as cold hands and feet, and joint chills in winter. Heating film can be applied to products such as mattresses, sofa cushions, knee and waist pads, etc. By continuously heating at low temperatures (usually 30-50 ℃), it gently increases local temperature, promotes blood circulation, reduces joint discomfort caused by cold, and has no open flames or noise. It is safe and suitable for elderly people to use.

• Individuals with constitution deficiency and coldness (such as females and postpartum populations)

Due to physical reasons, some women are prone to fear of cold in winter or experience abdominal and lower back pain during menstruation; Postpartum women are physically weak and have a higher need for warmth. Warm palace patches, heated seat cushions, bedroom wall warmers, etc. made of heating film can effectively alleviate local coldness, and the temperature can be adjusted (to avoid overheating), adapting to different tolerances.

• Children (requiring adult supervision for use)

Children have a high level of physical activity but weak ability to regulate their body temperature, making them susceptible to catching a cold while playing indoors in winter. Heating film can be used for children's room floor heating (such as underfloor heating film), baby crib mattress heating (low temperature range), to maintain stable ambient temperature and avoid catching a cold due to frequent clothing changes. However, it is necessary to choose products with overheating protection and have adult controlled switches.

Specific Health Needs Population: Assisted Therapy and Rehabilitation

• Joint disease patients (arthritis, rheumatism patients)

Patients with rheumatoid arthritis, cold legs, and other conditions are sensitive to cold, and low temperatures can exacerbate pain. The heating mat generates heat through far-infrared radiation (some product features), which can penetrate deep into subcutaneous tissue, promote blood circulation around joints, alleviate inflammation and muscle spasms. It is commonly used in shoulder pads, knee pads, therapy mattresses, etc. as an auxiliary rehabilitation method (with medical advice, temperature not exceeding 45 ℃).

• Sedentary/standing crowd (office workers, manual laborers)

Office workers who sit for long periods of time are prone to stiffness in their waist and back, while physical laborers who stand for long periods of time (such as teachers and salespeople) are prone to lower limb fatigue. Heated seat cushions, cushions, and foot heating pads made of heating film can relax muscles through local hot compress, alleviate soreness caused by prolonged sitting/standing, and improve comfort.

• Postoperative rehabilitation population

Some postoperative patients need to keep the wound or affected area warm to promote healing (such as joint warmth after orthopedic surgery). The flexible design of the heating film can fit the body curve, provide a stable local heat source, and the temperature is controllable (to avoid high temperatures affecting the wound), suitable for home rehabilitation scenarios (temperature and duration of use should be determined according to medical advice).

Special environment working/living population: cope with low temperature scenarios

• Outdoor workers (such as sanitation workers, construction workers)

Outdoor workers in winter face the challenge of severe cold, and the heating film can be integrated into clothing such as anti cold clothing, gloves, insoles, etc. It can be powered by a power bank to achieve portable heating, maintain core body temperature, and reduce the risk of frostbite (waterproof and wear-resistant industrial grade heating film should be selected).

• Low temperature environment practitioners (such as cold storage employees, cold chain logistics personnel)

In low-temperature environments such as cold storage and cold chain workshops, ordinary insulation measures are difficult to meet the demand. The heating film can be used as an inner lining for special work clothes and warm gloves, which can withstand extreme low temperatures through continuous low-power heating, and the material is lightweight and does not affect movement.

• Residents in northern rural areas/areas without centralized heating

For areas that are not connected to centralized heating, heating film can be used as a low-cost heating solution (such as wall heating film, floor heating film), installed in bedrooms, living rooms and other spaces, and turned on as needed to compensate for the shortcomings of traditional coal stoves and air conditioning heating (such as slow heating and high energy consumption), especially suitable for small-sized or rental households.

Other segmented demand groups

• Pet owners

Provide heating pads for pets (such as cats and small dogs) during low temperature seasons to prevent them from getting cold.

• Car drivers and passengers

When using the car in winter, the steering wheel cover and seat heating pad made of heating film can quickly heat up, relieving the cold discomfort after prolonged sitting.

• Precision instrument maintenance personnel

In low-temperature environments, heating film can be used to wrap instrument equipment (such as outdoor communication equipment, pipelines) to prevent malfunctions caused by low temperatures and ensure the normal operation of equipment.

In short, the applicable population of the heating film covers a wide range of needs from daily warmth to professional therapy, from home scenes to outdoor work. The core is to solve the problems of "cold discomfort" and "local temperature control" through flexible and safe heating methods.

Combined application with renewable energy

1. Integrated solar thermal storage system

• Paired with solar photovoltaic panels, utilizing low electricity prices at night for heating.
• Energy storage batteries are prioritized for supplying heating cables, achieving "spontaneous self use, surplus electricity heating".

2. Air source heat pump linkage

• In low-temperature environments (<-5 ℃), when the efficiency of the heat pump decreases, the heating cable automatically replenishes heat.

Through the above applications, heating cables have achieved an upgrade from basic heating to scenario based comfort solutions in civil buildings, especially in cold and "wet cold" areas, where their energy-saving and comfort advantages are more significant.

1、 Temperature control accuracy and stability advantages

• Closed loop control achieves constant temperature effect

The thermostat automatically starts and stops the heating cable by collecting temperature signals in real-time (such as PT100 sensor accuracy of ± 0.1 ℃), comparing them with the set value, to avoid significant fluctuations in "overheating cooling" of traditional heating methods (such as electric blankets).

Case: In a underfloor heating system, a temperature controller paired with carbon fiber heating cables can control the room temperature within a set range of ± 0.5 ℃ (traditional boiler heating temperature difference is usually ± 2 ℃).

• Flexible adaptation to different scene requirements

Programmable temperature controllers support temperature control in different time periods (such as 22 ℃ during the day and 18 ℃ at night), and with constant power heating cables, can customize temperature curves for greenhouse seedling cultivation, industrial pipelines, and other scenarios. Self limiting cables and mechanical temperature controllers are suitable for simple antifreeze scenarios (such as bathroom pipeline insulation).

2、 Energy utilization efficiency and energy-saving advantages

• On demand heating reduces ineffective energy consumption

The thermostat only activates the heating cable when the temperature is below the set value, avoiding heat waste caused by continuous heating. For example, in civil heating scenarios, compared to electric heaters that are constantly on for 24 hours, the temperature controller+heating cable system saves about 30% to 40% energy (data source: GB/T 39848-2021 Energy Efficiency Standard for Electric Heating Systems).

• Power matching optimization operating cost

The temperature controller is configured with a single load of 80% of the total power of the heating cable (leaving a 20% margin) to avoid power loss caused by the "big horse pulling small car". Taking 100 ㎡ underfloor heating as an example, a 2000W heating cable paired with a 2500W thermostat can reduce standby power consumption by approximately 120kWh per year compared to a 3000W thermostat.

3、 Advantages of system security and reliability

• Multiple protections to prevent overheating risks

The temperature controller is equipped with built-in overheat protection (such as setting an upper limit of 60 ℃ for forced shutdown), combined with the insulation layer of the heating cable (such as PE sheath with a temperature resistance of 90 ℃), which can prevent local overheating from causing fires. In industrial scenarios, explosion-proof temperature controllers and MI mineral insulated heating cables can better meet the requirements of hazardous environments (such as gas station pipeline heating).

• Convenience of fault diagnosis and maintenance

The digital temperature controller can display temperature abnormal codes in real time, and with the segmented detection of heating cables, it can quickly locate the fault point, improving maintenance efficiency by more than 50% compared to traditional heating systems.

4、 Advantages of application flexibility and adaptability

• Multi scenario customized solution

1. In the civilian field, temperature controllers and heating cables are installed in separate rooms to achieve differentiated heating of 22 ℃ in the master bedroom and 20 ℃ in the secondary bedroom;
2. In the industrial field, in the heat tracing of storage tanks, the temperature controller can be linked with a liquid level sensor (to strengthen heating when the liquid level is low) to avoid medium solidification;
3. In the agricultural field, heating cables are laid under the seedling beds, and the temperature controller automatically switches between "28 ℃ during the day/18 ℃ at night" to promote crop growth.

Compatible upgrade with intelligent systems

IoT temperature controllers (such as those with Modbus interfaces) can be connected to building control systems (BMS) and form an intelligent heating network with heating cables for "remote monitoring+big data analysis", suitable for large parks or data centers.

5、 Advantages in lifespan and maintenance costs

• Extend the service life of equipment

The "gap start" mode (non continuous operation) of the thermostat reduces the loss of heating cables during long-term full load operation. Carbon fiber heating cables can have a service life of 15-20 years under the control of the thermostat

• Reduce maintenance costs

The standardized interface between the thermostat and the heating cable facilitates the replacement of accessories, and the scale cleaning requirements of the waterless circulation system (compared to the water heating system) can reduce maintenance costs by more than 60% annually.

6、 Environmental and installation advantages

• Green, environmentally friendly, and pollution-free

The electric heating method has zero carbon emissions, and with the precise temperature control of the thermostat, it reduces about 2.3kgCO ₂/㎡ · year compared to gas boiler heating (taking Beijing as an example), which is in line with the trend of carbon neutrality.

• Easy installation and space saving

The heating cable can be laid in narrow spaces such as under the floor and on the surface of pipelines. The wall mounted installation of the temperature controller only occupies 0.02 square meters, saving 30% of installation space compared to traditional boiler+radiator systems.

The essence of the combination of the two is the deep integration of "intelligent control" and "efficient heating", which not only meets the basic heating needs, but also achieves multiple improvements in energy efficiency, safety, and experience through technological collaboration. It is the core technical solution of modern electric heating systems.

The response time of the heating mats protection system varies depending on the protection function, core components, heating mats type, and specific product. Here are some common response time introductions for protection functions:

Overheat protection

• At the hardware level: the temperature control switch generally operates within 1-5 seconds after the temperature exceeds the threshold (such as 70 ℃), causing the bimetallic strip to deform and disconnect the circuit. The response time of thermal fuses is relatively long. When the temperature suddenly rises, the low melting point alloy inside the fuse may melt within 10-30 seconds, permanently cutting off the circuit.

• At the software level: the control chip is pre-set with an "over temperature threshold". If the sensor detects that the temperature exceeds the set limit value (such as 65 ℃), it can usually immediately cut off the power and light up the fault indicator light within 1-2 seconds.

Leakage protection: Insulation resistance monitoring can generally immediately power off and alarm within 1-2 seconds after detecting leakage current exceeding the set value (such as 0.5mA). The grounding protection (PE line) is combined with the residual current device (RCD), and in the event of leakage, the RCD can usually trip and cut off the power supply within tens of milliseconds.

Short circuit and overload protection: When the current exceeds the rated value, the fuse usually melts within 1-5 seconds. The overcurrent detection circuit monitors the current through a sampling resistor. If the current suddenly increases, the chip can cut off the MOS transistor switch within 10 milliseconds, and the response speed is much faster than traditional fuses.

The response time of the protection system varies for different types of heating mats. Traditional electric heating wire heating mats, due to the use of relatively simple protective devices, may have an overall response time of several seconds to tens of seconds; The carbon fiber smart and aluminum foil self temperature limiting high-end heating seats, with the help of advanced sensors, chips, and control algorithms, can usually shorten the response time to less than 1 second, and some high-end products can even reach millisecond level.

Carbon fiber endows its composite materials with excellent properties due to its inherent characteristics, including high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, conductivity, heat transfer, and low coefficient of thermal expansion. This provides the possibility and inevitability for its application in the wire and cable industry.

Development and Application of Carbon Fiber Heating Cable:

People have long known that electric heating technology using metal materials as heating elements has been widely applied in various fields. However, metal wires are prone to oxidation on the surface at high temperatures. Due to the continuous thickening of the oxide layer, the effective area for current flow decreases, increasing the current load and making them prone to burning out. Under the same allowable current load area, the strength of metal wire is 6-10 times lower than that of carbon fiber, and it is prone to breakage during use.

Carbon fiber is a hexagonal lattice layered structure composed of graphite, and is a fully black body material. Therefore, in electric heating applications, it exhibits high electric thermal conversion efficiency. Under specific conditions, high temperature does not oxidize, and the load intensity and mechanical strength per unit area of current do not change.

The current applications of carbon fiber heating cables are as follows:

Low temperature radiation heating cable floor heating system.

Thermal insulation heating for constant temperature brooding boxes, flower rooms, nurseries, vegetable greenhouses, etc.

Road snow melting and airport runway snow melting: Ideal products for floor heating in concrete structures, can also be used in snow melting devices to prevent frost on roof rainwater and drainage pipes, and can be used for soil heating.

Pipeline and tank insulation and antifreeze: Electric heat tracing products have been widely promoted and applied in China in recent years. Its application areas mainly focus on petroleum, chemical, power, railway, and civil or commercial buildings. With the development of China's power industry, the market prospects for electric heat tracing products, which mainly rely on clean and pollution-free electricity, are very broad. At the same time, higher requirements have been put forward for the performance of electric heat tracing products.

Soil insulation for football fields, lawns, and public green spaces: Solar water heaters are designed to supplement heat energy when the water temperature of the solar water heater cannot meet the needs of daily life or engineering due to insufficient sunlight during long-term rainy or winter seasons. It has strong resistance to extreme heat, cold, and high temperature and humidity environments, and has the function of preventing dry burning. Even if the water tank is occasionally short of water and accidentally powered on, it will not burn out the electric heater and water tank, ensuring safe use.

Efficient and energy-saving:

The electric heating conversion rate exceeds 98%, which is more energy-efficient than traditional resistance wire heating (conversion rate of about 80%) and meets the "dual carbon" goal.

Fast heating rate:

It can heat up to the target temperature (such as 50 ℃~100 ℃) within seconds, with a faster response speed than traditional PTC heating elements.

Good temperature uniformity:

In the planar heating mode, the temperature difference can be controlled within ± 2 ℃ to avoid local overheating, making it suitable for scenarios that require high temperature accuracy.

High safety:

No open flames, low electromagnetic radiation, and with insulation layer design (such as PET/PI substrate wrapping), it can achieve water and electricity separation.

Strong design flexibility:

Customizable size, shape, and power according to requirements, suitable for special scenarios such as flexible wearable devices and curved heating devices.

Introduction to heated seats:

The underfloor heating mat is equipped with alloy or carbon fiber heating elements as heating components, which have stable heating performance, no power attenuation, and high infrared emissivity. Two layers of 0.1mm thick aluminum foil are used as the thermal conductive layer and shielding layer. The temperature distribution of the entire heating mat is uniform during operation, without overheating points, and the electromagnetic radiation is 0. The high-temperature fiberglass mesh serves as the skeleton of the entire geothermal mat, enhancing its tensile strength and impact resistance. And it has an automatic temperature limiting function, so the heating mat will not burn the insulation board below and the wooden floor above due to overheating.

Characteristics of heated seats:

1. Fast heating and rapid warming. It only takes 10-15 minutes to reach the room temperature you need.

2. Thin structure and light weight. Not occupying the floor height and space of your room.

3. Safety and energy efficiency.Using high-temperature insulation and fully sealed aluminum foil shielding, the entire system can operate for a long time in an environment of 120 degrees Celsius. The electromagnetic radiation value is 0. The entire system is waterproofed and can work in humid environments. The drainage line (ground wire) ensures the safety of the system. This heating mat is 20-25% more energy-efficient than heating cables of the same power

4. Self limiting temperature function, allowing you to achieve comfortable room temperature and energy-saving safe heating operation system.

5. Convenient construction, the heating core of the heating mat is arranged in a double conductor layout, and there is also a turning design for the heating mat, making construction particularly convenient, 5-6 times faster than laying heating cables of the same power.

North American Market:

The North American region is one of the important global markets for electric trace heating cables. Benefiting from its well-developed industrial system and strict environmental protection regulations, there is a strong demand for efficient and environmentally friendly heating solutions. Especially in the United States, it is widely applied in industries such as oil and gas, and chemicals.

European Market:

The European market places great emphasis on technological innovation and sustainable development, and has a high acceptance of intelligent, energy-saving and environmentally friendly electric trace heating systems. Countries like Germany and the United Kingdom have particularly prominent applications in the fields of industrial automation and building thermal insulation.

Asia-Pacific Market:

In the Asia-Pacific region, especially in China, with the rapid economic development and the acceleration of the industrialization process, the demand for electric trace heating cables continues to grow. At the same time, the extreme climatic conditions in the Asia-Pacific region have also promoted the widespread application of electric trace heating technology in areas such as pipeline anti-freezing and agricultural greenhouses.

Summary and Outlook:

In conclusion, as an efficient and environmentally friendly heating solution, electric trace heating cables are being widely used and developing rapidly around the world. Their remarkable advantages not only meet the temperature control requirements of various industries but also make important contributions to energy conservation, emission reduction, and the promotion of sustainable development.In the future, with the continuous advancement of technology and the expansion of the market, electric trace heating cables are expected to achieve application innovation in more fields. At the same time, they will face challenges and opportunities in aspects such as intelligence, customization, energy efficiency, and energy conservation. In this process, continuous technological innovation and market expansion will be the key for enterprises to maintain their competitiveness.
