INQUIRY

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.

If you have special requirements please feel free to message or email us!
