ZC-3241
ZC-3241 Silane XLPE Compound of Monosil Method for Aerial Wire and Cable up to 10KV
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: 10kV and below aerial cable insulation; Maximum working temperature is 90C. Property

- Above temperature is only for reference.
Reference cross-linking conditions
For general cable insulation layer (1 mm in thickness) can be cross-linked after bathed in 90C 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
Keep at room temperature; Storage environment should be clean, dry and ventilated; Best use within six
months from the date of production; Please use up in 16 hours after bag is opened.
Product packing
25kg in moisture resistant aluminum laminated bags with composite paper bags outside; Palletized bottom.
