Ⅰ.Composition and Application
Type HXGN口-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 50/60Hz. 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.This equipment is widely used in urban power grid transformation, residential areas, high-rise buildings, industry, mining, hotels, shopping mall, airport, railway, oilfield, wharf, highway and temporary power facilities.
