HXGN-12 air insulated ring main unit switchgear with SF6 switch

HXGN-12 air insulated ring main unit switchgear with SF6 switch

HXGN-12 ZFR type fixed metal closed switchgear air insulated with vacuum load switch is a complete set of AC HV electrical equipment with rated voltage from 12kV to 35kV and rated frequency of 50Hz. It is mainly used in three-phase AC ring network, terminal distribution network and industrial electrical equipment for receiving and distributing electric energy. It is also suitable for installation inside of the compact substation with IP54. It is similar design idea as SM6 or Uniswitch, So we can use it as best replace of economic type switchgear of SM6 or Uniswitch.
