ZC-3211 Silane XLPE Compound of Sioplas Method for Aerial Wire and Cable up to 10kV
ZC-3211 Silane XLPE Compound of Sioplas Method for Aerial Wire and Cable up to 10kV
Description
This material is a kind of warm water crosslinkable polyethylene insulation compound which consisted of compound A and compound B. Compound A is made from high quality polyethylene resin, imported silane coupling agent and compound B is made from organotin catalysts and antioxidant agent. Loss-in-weight Feeder which guarantees stable precision of components. It has an excellent extrusion performance and stable physical and chemical index.
Application
- 3kV and below aerial cable insulation;
- Maximum working temperature is 90℃.
