Overview
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.
Working Conditons
1.Working environment temperature: upper limit +40ºC, lower limit: -25ºC.
2.The altitude of the use site shall not exceed 2000m.
3.air relative humidity: daily average is not more than 95%, monthly average is not more than 90%.
4. the surrounding air is not corrosion or combustible gas, water vapor and other obvious pollution.
5. no frequent violent vibration.
