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:

---|---|---|---|---|---|---|
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.
