An alternative to SF6 in electrical switchgear - EE Publishers decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. However, SF6 is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with […]

Siemens receives order for world's first SF6-free gas ... order includes three bays of the 8VN1 gas-insulated, SF 6-free 145 kV switchgear. This GIS uses vacuum interrupters for switching functions and treated air, known as "clean air", as the insulating medium. It is therefore possible to completely eliminate the use of sulfur hexafluoride.

Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
