Purpose and Significance of Substation Cleaning

Substation equipment such as transformers, circuit breakers, voltage transformers, current transformers, surge arresters, isolating knife switches, reactors, etc., have porcelain sleeves and rod supports that provide electrical insulation and mechanical support. Environmental pollution can significantly reduce the external insulation level of these devices, leading to pollution flashovers. Regular cleaning of substations is crucial to prevent accidents caused by a decrease in the external insulation level.
