Problems solved by technology

[0002] At present, the power cable casing is mainly made of polyvinyl chloride material in production and application. This material has the advantages of good corrosion resistance, processing performance, and low cost, but its heat resistance is not high, low strength, high brittleness, and impact resistance. Poor performance, poor flame retardant effect, easy to break during production, transportation and construction, and prone to transmission failures in environments with high heat generation, large amount of information transmission, and harsh transmission environments
It has been reported that CPVC materials are used to prepare power cable pipes. Although its performance is greatly improved compared with PVC casings, the cost of the products is high, the weather resistance is poor, and the temperature resistance is not high enough, especially not suitable for high-voltage power under harsh environmental conditions.
