Fire resistant wire and cable (Fireproof wires, Fire rated wires) can maintain the integrity of wire and cable lines and the normal operation of line equipment for a certain period of time while the external flame is still burning in the fire accident of wire and cable.


We use the Glassfiber+ Mica and Fireproof silicon materials to be the insulation.


Below is our fire resistant wire infor. of types,cable structures,specifications,etc.
