Peroxide Crosslinked Semiconductive Shielding Material for Conductor of XLPE Insulated Cable

Crosslinked Semiconductive Internal Shielding Material 35 KV and Below


Product introduction

This project is a semi-conductive shielding material obtained by mixing, plasticizing and extruding granules with polyolefin as the base material, conductive carbon black and various specific additives.

Product Features

·Excellent Conductivity                   ·Excellent anti-aging properties

·Excellent processability             ·Excellent peelability

· excellent mechanical properties

Usage features

Cross-linked semi-conductive shielding materials are suitable for cable conductors and allow a maximum operating temperature of 90 ° C for long periods of time.

Thermoplastic semi-conductive shielding materials are suitable for cable conductors and allow a maximum operating temperature of 70 ° C for long periods of time.

Processing Guide

It is suitable for processing on the existing screw equipment of power cable, and can obtain good extrusion process effect.

Recommended processing temperature:

Zone 1# 2# 3# 4# 5# Head
Temp(℃) 80 85 90 95 100 110

Storage and packaging

The semi-conductive shielding material should be stored in a clean, dry and ventilated warehouse. The storage temperature should not be lower than 0 °C, and the stacking height should not exceed three boxes. The storage period shall not exceed six months from the third day of production.
The semi-conductive shielding material should be packaged in moisture-proof packaging. The inner bag is made of PE composite film bag. After being sealed and packaged, it is packed into a hard corrugated cardboard box which is not easy to be damaged. The waterproof film of the outer casing is 500Kg± 1Kg per box.
