XGN66A-12 fixed metal-clad movable switchgear (hereinafter called switchgear), is used in the system of rated voltage 3.6- 12KV three-phase, AC50/60Hz,
XGN66A-12 fixed metal-clad movable switchgear
to receive and distribute electricity, suits for frequently switching, or reconstruction of switchgear with oil type breaker. Busbar system is single busbar system or single busbar with branches. Comply with GB3906 AC metal-enclosed switchgear and controlgear for rated voltages above 3 kV and up to and including 35 kV, DL/T404 Purchase technical specifications for indoor AC high voltage switchgear, IEC60298 AC metal-enclosed switchgear and controlgear for rated voltage above 1 kV and up to and including 52 kV standard The switchgear has good figure, small size provides complete prevention of the wrong operation. The main switch o the switchgear adopted VS1-12 or ZN28-12 vacuum circuit breaker type GN30-12 or GN19-12 isolator, and JN15-12 earth switch
