1. 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℃.
