Product Description
1. Application
XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric strength, mechanical strength, high-ageing resisting, environmental stress resisting aiti-chemical, corrosion, and simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction. Various of flame-retardant XLPE cable can be manufactured with three technology. The flame-retardant cable covers all kinds of low-smoke, halogen free, and non-smoke non-halogenated and three classes of A,B,C.
