The XGN 12 box-type fixed metal-enclosed switchgear is a high-voltage assembled switchgear developed by Xi'an High Voltage Apparatus Research Institute. The main primary components used in the equipment are newly designed, offering higher insulation levels and protection ratings compared to the currently prevalent truck-type switchgear and GG-1(A)F type switchgear. The design does not include any form of phase-to-phase or phase-to-ground barriers or insulating gas. The secondary circuit does not use secondary plugs (meaning that the protection and control circuits are always continuous regardless of the device's state). This product is used for 3-10 kV single busbar systems, serving as high-voltage assembled equipment for receiving and distributing electric energy. The product meets the "five prevention" requirements, and all its indicators comply with GB3906 "3-35 kV AC Metal- Enclosed Switchgear" and IEC 298 technical standards
