The mica tape has high temperature resistance, the silicone rubber has high insulation performance, and the polycarbonate has flame retardancy, oxidation resistance and wear resistance. The multi-layer structure increases the high temperature resistance and flame retardancy of the cable.

The conductor will generate a certain amount of heat when in use. When the heat is too high, it will affect the normal use of the conductor and further shorten the service life of the conductor.
