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.
