Flexible Mica Insulated Fire - Proof Cable 

1. Structure sketch for flexible fire proof cable

1) Cable conductor: It is made up of stranded copper wires, with favorable flexural property.

2) Insulation layer: It adopts high-temperature resistant inorganic insulating materials.

3) Inorganic stuffing: It adopts special stuffing material - glass fiber tape which is low-smoke and non-toxicity.

4) Outer sheath: It is made of mental materials of copper or stainless steel with favorable corrosion protection.
