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.
