XGN□ – 10 Case Fixed Metal-Enclosed Switchgear is a kind of high voltage apparatus developed and researched out by Xi’an High Voltage Apparatus Research Institute.   Compared with currently used truck type switchgear such as GG – 1(A)F, it owns higher insulating level and protective level since main primary components in cubicle are re-designed and not any kind of partitions or insulating gaseous set between phases and from phase to earth.  As there is no secondary plugs for connection for the secondary circuit, the protective and control circuits are always energized at any status of the equipment.   The product is widely applied in 3 – 10kV single busbar and that  with bypass electric systems for electricity acceptance and distribution.

 

Meeting the “Five Preventives” requirement, the product complies GB3906 “3 – 35kV AC Metal-Enclosed Switchgear” and IEC 298 standard in terms of each parameter.
