Product Details

一、Overview
  

indoor AC box-type metal-enclosed switchgear (switch cabinet for short) is a new type of indoor compact power supply and distribution equipment jointly developed and produced by our company and China Electric Power Research Institute.

The ZN100-12 vacuum circuit breaker and FZN58-12 vacuum load switch selected in the XGN68-12 switch cabinet adopt vacuum interrupter epoxy resin sealing technology. They have beautiful appearance, good insulation performance and easy operation. The cabinet adopts a patented rotary fuse structure, which makes the fuse replacement pull-out, which is particularly convenient.

The XGN68-12 switch cabinet has the smallest overall dimensions among air insulated cabinets. It meets environmental protection requirements for power supply and distribution in urban users and residential areas and has the smallest effective floor area. The XGN68-12 switch cabinet is the most ideal choice.
