2021/7/19What is High Voltage Switchgear. (Explantation) The power system deals with voltage above 36KV, which is referred to as high voltage switchgear. because the voltage level is high the arcing produced during switching operation is additionally very high. So, special care is to be taken during the designing of high voltage switchgear.

The insulating properties of commercially available insulating materials are determined by the amount of gas held inside the material and the number of gas pockets. Therefore, the higher the number of cells (which can maintain the gas stagnant) and the smaller their size, the lower the thermal conductivity of such insulating material.
