XLPE  insulated High Voltage Power Cable

 

XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE power cable has high electric strength, mechanical strength, high-ageing resisting, environmental stress resisting anti-chemical corrosion, and it is simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.

The flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology (peroxide, silane and irradiation cross-linking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free, and non-smoke non-halogenated and three classes of A,B,C.
