Structure and performance


GN38-12D upper isolating switch structure design is novel, reasonable and unique. The outgoing line adopts the through-wall type, which directly forms an insulating partition in the busbar room and the circuit breaker room. Its incoming terminal is easy to be directly connected with the horizontal busbar of the parallel cabinet, which can reduce the height of the switch cabinet, reduce the transition joint and reduce the cost.


The operating mechanism drives the isolating switch shaft to rotate, and drives the operating arm to push and pull the isolating blade, so that it opens and closes with the incoming line contact, or with the grounding contact to achieve isolation or grounding.
