  • An alternative to SF6 in electrical switchgear - EE Publishers

    For 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 […]

The challenge is aimed at finding alternative solutions to the use of SF6 gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (SF6) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, SF6 is also an extremely potent greenhouse gas with
