Application

BVN

Copper conductor PVC insulated nylon sheathed wire

Fixed-wired for construction, electrical apparatus and switch

BVN—90

Copper conductor 90℃ PVC insulated nylon sheathed wire

Fixed-wired for construction, electrical apparatus and switch upon heat-resistance requirement

BVNVB

Copper conductor PVC insulated nylon and PVC sheathed flat cable

Fixed-wired for construction

The PVC insulated nylon sheathed wire has advantages with excellent thermal stability, larger mechanical strength and surface strength, anti-thermal-distortion, better bending strength and impulse strength, abrasion resistance and chemical-resistance and self-lubrication as well as better machine-oil-resistance and gas-proof. The PVC insulated and nylon sheathed wire has advantages with less overall diameter and lighter than PVC insulated wire, better self-lubrication to be easily installed and providing better safety with less damage that be poling.
