Under 35KV XLPE insulated PVC sheath power cable
XLPE insulated PVC sheath power cable is used for rated voltage up to and including 35KV as power lines to carry electric power. The flame retardant power cables are especially suitable for use in hotels, railway station, chemical plants, oil refinery petrochemical plants, mines, power stations, sub-ways and high-rises where flame retardant cables are required.
In XLPE insulated power cables, a chemical or physical cross-linking method is used to make the straight chain of polyethylene molecule to become a three dimensional network, thus improving greatly the mechanical properties, heat-ageing characteristics, resistance to environmental stress cracking. The resulting cable feature excellent electric properties and chemical resistance, simple construction, easy to operate, small overall diameter, light weight and installation irrespective of drop in elevation. XLPE cables have higher long term operating temperature than paper or PVC insulated cables. So they feature increased capacity and greater overload capacity.
