what is the purpose of using semiconductors in HT cables..

Answer / bhavuk sharma

The semi conducting material is used in HV cables to reduce the stress caused on insulation due to high electric field.
This can be achieved by gradually reducing the electric stress. Now to gradually reduce this stress a layer of semi conducting material (since it is neither a complete insulator or a complete conductor) is used just before the main insulating compound of cable. This will reduce the electrical stress on this main insulating compound.
