Using solid sealing pole technology.
The product adopts modular design: frame structure, integrated isolation switch, solid sealed vacuum circuit breaker, ground switch, sensor, interlock mechanism, operating mechanism as one of the high-performance miniaturized high voltage electrical products. Rotary isolation switch with visible fracture after opening.
There is a forced mechanical interlock between the isolation switch, circuit breaker and ground switch to prevent misoperation.
