XGN66-12 Box-type fixed metal-enclosed switchgear
XGN66-12 box-type fixed AC metal-enclosed switchgear (hereinafter referred to as switchgear) is suitable for 3.6~12k V three-phase AC 50Hz system as a device for receiving and distributing electric energy, suitable for frequently operated places and equipped with oil switches Used for the transformation of the switch cabinet. The bus system is a single bus system and a single bus section system.
The switchgear meets the requirements of GB3906 "3.6-40.5kV AC Metal-enclosed Open Sky Equipment and Control Equipment" and DL404 "Technical Conditions for Ordering Indoor AC High Voltage Switchgear". The switchgear has beautiful appearance, small size and complete and reliable misoperation prevention. Features. The main switch installed in the switchgear is VS1-12 or ZN28-12 vacuum circuit breaker, the isolation switch adopts the GN30-12, GN19-10 type isolation switch, and the grounding switch adopts the JN15-12 type grounding switch.
