Environment-friendly nano-composite high polymer control cable

[0003] At present, the cables sold on the market include low-smoke and halogen-free control cables, ant-proof or rodent-proof control cables, waterproof control cables, flame-retardant control cables, fire-resistant control cables, flame-retardant and fire-resistant control cables, etc. The main safety performance of these cables is Monotonous, unable to meet the needs of two or more safety performances; light rail subways, nuclear industry, airports, stations, offshore platforms, hospitals, office buildings and other public places with relatively concentrated personnel, as well as important areas of industrial and mining enterprises require cables to have high environmental performance and High-strength performance. At the same time, these areas are also places where termites or rats are rampant. The cables are required to have anti-ant and rodent performance. The places where people are concentrated also require that the cables can be guaranteed to run for a period of time in case of fire to ensure that people have enough time to escape. The above places There is more or less water or water vapor in the cable channel, which requires the cable to have good water resistance and high strength performance, so the cables with single safety performance used in the above places cannot guarantee safe operation
