Unique transmission structure design, arc extinguishing chamber only at the moment of closing and breaking withstand high pressure, so small volume and light weight.
It can realize one-time operation of isolation fracture and interrupter fracture.
Between the static contact and the moving contact head guide torch, there is a grounding valve linked with the grounding switch, which not only ensures safety but also facilitates maintenance.
