Applications Guide· PDF fileFor 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. This gas has a higher insulating value than air, allowing the dimensions of the apparatus to be reduced.
