Minimum External Insulation Distance Of Insulating Sleeve

Switchgear Insulating Bushing The minimum external insulation distance is a parameter that needs to be focused on in the design of power equipment, which is directly related to the safety and stability of equipment operation. Simply put, this distance refers to the shortest air path from the outer surface of the bushing to the grounded part or the adjacent conductor, and it must be ensured that no breakdown or flashover occurs under various working conditions. The following is a detailed explanation of the influencing factors, design ideas, and precautions in practical applications.
