main technical parametersLoad switch technical parameter table
The load switch is an oil-immersed, three-phase linkage switch with, spring operating mechanism. It can be operated with load division and brake, and its division and speed have nothing to do with the size of the operating force. There are two stations, four stations T-type, four stations V-type, and so on.
