XGN2-12 Box Type Fixed AC Metal-enclosed Switchgear (referred to as switchgear) is used for receiving and distributing electrical energy in power systems with a rated voltage of 3.6-12kV, three-phase AC 50Hz, and rated current of 630-3150A. It is especially suitable for occasions requiring frequent operation. Its bus system is a single bus, and single bus with bypass or double bus systems can be derived.
The switchgear conforms to the requirements of the national standard GB3906 “3-35kV AC Metal-enclosed Switchgear” and the international standard IEC 298, and has a perfect anti-misoperation function.
The main switch of this switchgear adopts ZN28A-12 series, ZN28-12 series, and other vacuum circuit breakers, while the isolation switch adopts GN30-12 rotary isolation switch, GN22-12 high-current isolation switch, and GN30-12 rotary high-current isolation switch series products.
