Indoor Gas Insulation Metal-clad Switchgear DXG-40.5(z)

DXG-40.5(z) Indoor Gas Insulation Metal-clad Switchgear ( hereafter referred to as "GIS") is high tech products, which are researched, developed and manufactured by introduction of technology from Long Yuan Electric Power Research Institute, affiliated with China Electric power Federation. Besides it is up to GB/T11022and GB3906 [3-35KV AC Metal-clad Switchgear] standard. It is featured by high reliability, free of maintenance, less occupied area; The main technical parameter has reached an international advanced level.

Product feature :
      The DXG-40.5(Z) GIS is suitable for power plant, substation, combined substation and electric power system, which is three phase indoor AC single busbar and sectioning single busbar with 50HZ, 35kV rated voltage, used to control, accept and distribute electric power.

Service ambient condition :
      Air temperature: Max: +40ºC, Min:-25ºC (average is not more than 35ºC in 24 hours)
      Altitude above sea level: <= 3000m
      Air humidity: the average relative humidity measured in 24 hours is not more than 95%, the average relative humidity per month is not more than 90%, average water vapor pressure measured in 24 hours is not more than 2.2kPa, average water vapor pressure per month is not more than 1.8 kPa.
     Without frequent heavy vibration
     The range of induction electromagnetic interference of secondary system is not more than 1.6kV
     Conditions excluded from above are in need of negotiating with the manufacturer.
