ZC-3101 Peroxide XLPE Insulation Compound for MV Cable up to 10kV

ZC-3101  Peroxide XLPE Insulation Compound for MV Cable up to 10kV

 

 

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

10kV crosslinkable cable insulation;

- Maximum working temperature is 90℃.
