Product Description

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℃.
