ZC-4211 35kV Outer Strippable Semiconductive Shield Compound

 

ZC-4211 Outer Strippable Semiconductive Shield Compound for MV Power Cable up to 35kV

 

 

Description

This material is used for crosslinkeble semiconductive shielding material. It is produced by using high quality EVA resin, conductive black carbon as the main material, adding cross-linking agent, antioxidant and other additives; mixed granulation and fabrication process is stable and reliable in quality.

 

Application 

Shielding material of 35kV crosslinkable polyethylene insulated cable insulation layer; 

-  Maximum working temperature is 90℃.
