  Feb 08, 2021 · Depending upon the design of the switchgear, oil or insulating gas gas is to be filled as an insulating medium. After drying out of the switchgear, proper oil level or proper pressure of Sulfr hexafluoride gas needs to be maintained as per the manufacturer's recommendations. In many designs, poles are filled with nitrogen gas above atmospheric pressure (1.5/2 times ofGet price
  For higher voltages, gas-insulated switchgear reduces the space required around live busbars. Instead of bare conductors, bus and apparatus are built into pressurized tubular containers filled withsulfur hexafluoride (sf6 gas) gas. This gas has a higher insulating value than air, allowing the dimensions of the apparatus to be reduced.Get price
