ZC-3111 Peroxide XLPE Insulation Compound for MV Cable up to 35kV
ZC-3111 Peroxide XLPE Insulation Compound for MV Cable up to 35kV
Description:
This material is a kind of crosslinkable polyethylene insulation compound. It is made of high quality PE resin, dicumyl peroxide agent and antioxidant agent by plasticizing granulation. Production process uses the closed system; Loss-in-weight Feeder which guarantees stable precision of components. It has stable physical and chemical index and good processing property.
Application:
- 35kV crosslinkable cable insulation;
- Maximum working temperature is 90℃.
