Type HXGNO-12 box type fixed metal closed switchgear (referred to as ring network cabinet) is a complete set of AC high voltage
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 loading into box type substation.
