450/750v Rubber Insulated Cable 2*1.5mm 2.5mm2 4mm2 6mm2 Silicone Rubber Insulated Flexible 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, environment stress resisting anti chemical corrossion, and it is simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.It is widely used in electric power,construction,mining,metallurgy,petrochemical,transportation etc.
