タイトルまたは説明

AL/Aluminium conductor XLPE insulated cable
copper or aluminium XLPE Insulated Power Cable YJLV*2 0.6/1KV

XLPE Insulated Power Cable        YJLV*2 0.6/1KV 4X**0

Rated voltage: 0.6/1kv

Norminal thickness of insulation: 1.2mm

Approx. overall diameter: *6.2mm

Max cable weight: ***0kg/km

Nominal cross sectional area of conductor: 1.5~**0mm2 

For XLPE insulated power cable ,either chemical method or physical method is employer to transform the molecular structure of PE form chain into three-dimensional network, i.e. thermoplastic PE is transformer into thermosetting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent property are still retained.

The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is *0 which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application  besides its excellent electrical, thermal ,mechanical and anti-chemical corrosion properties. It can also be laid with  no limitation of level difference along the route.
