40.5kV Gas-Insulated Switchgear

Product Detail

XD Baoji Electric Co.,Ltd is one of the leading China 40.5kv gas-insulated switchgear manufacturers and suppliers, as a professional company, our factory is able to produce quality 40.5kV GIS, 40.5kv gas-insulated switchgear products at competitive price.

 Product Description
      XGN46-40.5 series C-GIS is three-phase A.C 50Hz indoor complete distributing equipment with the voltage range 40.5kV. It is used for power distribution system, such as power plant, substation, industrial enterprise, urban rail transit and metro to receive and distribute power. Especially suitable for high humidity, condensation, high altitude, and dirty environments.
      The structure of this C-GIS is metal enclosed, cubical fixed, the gas-filled compartment of the C-GIS is made of stainless steel by way of laser welding. It can be equipped with three-position disconnector and circuit breaker. The wrong operation can be avoided due to its function of the ‘FIVE PROVENTION’. It can meet the standard requirments of IEC62271-200?IEC62271-1?GB3906?GB/T11022 etc.
      Overall dimension (W×D×H mm):800(600)×1650×2350.
