Product introduction
XGN66-12 box type fixed metal enclosed switchgear (hereinafter referred to as switchgear) is suitable for use as a device for receiving and distributing electrical energy in 3.6-12kV three-phase AC 50Hz systems, and is suitable for frequent operation places and switchgear retrofit with oil switches. The busbar system consists of a single busbar system and a single busbar segmented system.
The switchgear meets the requirements of GB3906 “3.6~40.5kV AC Metal Enclosed Switchgear and Control Equipment” and DL404 “Technical Conditions for Ordering Indoor AC High Voltage Switchgear”. The switchgear has a beautiful appearance, small size, and complete and reliable anti misoperation function. The main switch VS1-12 or ZN28-12 vacuum circuit breaker installed in the switchgear adopts GN30-12 and GN19-10 isolating switches, and the grounding switch adopts JN15-12 grounding switch.
