Product Description

Characteristics
Heat shrinkable compound double wall pipe made of heat shrinkable insulation material and heat shrinkable semiconductive material by the way of special processing technology.Inner layer show good insulation performance,outer layer is of semi-conductive,inner and outer layers are clung closely, shielded reliably.

Application
It is used for the insulation and outer shield of medium joint in 35KV and below power cable, and others where it needs for the insulation and shield.
