Solution

Cable: cable consisting multinumber independent conducting wires and it is enclosed by insulating materials like PVC, impregnated paper insulation, armored cable etc... this types cables generally used under ground transmission systems.

Practically different types of cables are available.

low voltage cables (LV) 50V - 1000V PVC or PE

Medium Voltage (MV) 3kV - 150kV PVC, PE,XLPE,EPR

High voltage (HV) 10kV - 150kV SF6, XLPE.

Very high voltage (VHV) 150kV - 300kV XLPE SF6, paper.
