ZC-3232 Silane XLPE Compound of Monosil Method for Wire and Cable up to 3kV

 

ZC-3232  Silane XLPE Compound of Monosil Method for Wire and Cable up to 3kV

 

 

Description

This material is a kind of warm water crosslinkable polyethylene insulation compound. It is processed by using high quality polyethylene resin, silane coupling agent, initiator, antioxidant agent, catalyst and other additives. It has an excellent extrusion performance, stable physical and chemical index; Quick extruding speed and smooth surface.

 

Application

- 3kV and below power cable insulation;

-  Maximum working temperature is 90℃.

Reference cross-linking conditions

For general cable insulation layer (1 mm in thickness) can be cross-linked after bathed in 90℃ above hot water for 4 hours. If the thickness of insulation is larger, it should be appropriate to extend the bath time. Extended by 1mm/4h or extend the time according to the specific heat for extended data.

 

Storage
