Product details

XGN49 Series lndoor Gas lnsulatlon MetaI-clad Switchgear(hereinafter called C-GlS)is a high quality product which the China power industry federation sole recommends technology from Korea Rijin electrical equipment industry corporation and it meets Chinese standards of GB/T11022-1999 and GB3906-2006C-GlS.
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: +40, Min: -25 (average is not more than 35 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.
