ZC-4201 10kV Outer Semiconductive Shield Compound
ZC-4201 Outer Semiconductive Shield Compound for MV Power Cable up to 10kV
Description
This material is used for crosslinkable 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 10kV crosslinkable polyethylene insulated cable insulation layer;
- Maximum working temperature is 90℃.
