XGN2-12 box type fixed AC metal-enclosed switchgear (hereinafter referred to as switchgear) is used for receiving and distributing electric energy in 12kV and below three-phase AC 50h system, especially suitable for frequent operation occasions. Its bus system is single bus (and can be derived from a single bus with bypass and double bus structure.
XGN2-12 box type fixed AC metal-enclosed switchgear is a plateau type product derived from ordinary switchgear and suitable for use in high-altitude areas. It has a perfect "five prevention" locking function.
The switchgear meets the requirements of the national standard GB39063-35kv AC metal-enclosed switchgear, GB / T 11022 common technical requirements for high voltage switchgear and control equipment standards, IEC 60298 AC metal-enclosed switchgear and control equipment with rated voltage above 1kV and below 52kv and ec6064 common terms for high voltage switchgear and control equipment.
