ZC-3111 Peroxide XLPE Insulation Compound for MV Cable Up To 35kV
-
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℃.
