Product Description
Insulation cable paper for motor winding insulation
All paper with 100% unbleached sulphate pulp copied into, the outermost layer of the cable to protect the conductive core insulation seal, not to moisture intrusion, do not let the destruction of the insulating layer, paper tough, Leveling. A higher tensile. For high-voltage power cables, control cables and signal cables with an insulating paper. It packs in the outermost layer of the cable to protect the conductive core insulation seal, not to moisture intrusion, do not let the destruction of the insulating layer. For the web.
Features
