20kV steel wire or steel tape armoured cable

12-20kV (12.7-22kV) Armoured Cable

XLPE Insulated Medium Voltage electrical cable manufacturer

Application

XLPE(Cross linked polyethylene) cable constitutes the best cable for transmission and distribution lines because of its excellent electrical and physical properties. These cables 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.
