Combined Fixed AC Metal Clad Switchgear XGN2-12(Z)
XGN2-12(Z) Combined Fixed Metal-clad Switchgear (hereafter referred to as switchgear) is suitable for 3-10 kV three-phase AC 50 HZ system for power transmission and distribution and specially used in places with frequent operation. The busbar system is single busbar, as well as single busbar with by-pass and two-busbar structure. The switchgear satisfies the requirement of national standard GB3906-91 [3-35kV alternative current metal-clad switchgear] and IEC 298 and has Wu Fang function. And the altitude height is 4000m.
Product feature :
It adopts metal-clad structure and its frames are welded by profile steel and high quality cold rolled sheets. It is made up of fuse room, busbar room, cable room, relay room. They are separated by steel plates. So there is enough space for examining and repairing and then the complex protection function of relay can realize. The width and height of plateau switchgear are increased much more than the ordinary switchgear, but the height is kept as it is. The clearance of electrical appliance is more than 150mm.
