what is the purpose of using semiconductors in HT cables
Answer Posted / 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.

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses? the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
