dilo GCB SF6-alternative gases technical

For decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. 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 insulation […]

  • VALIDATION METHODS OF SF6 ALTERNATIVE GAS

    From a technical point of view, one of the most important technical challenges during the selection of alternative gas to SF6 is related to the insulating properties of potential candidates. Indeed, as SF6 is used for several decades, its insulating properties and consequently the theoretical rules to

  • Green Switching: A sustainable alternative for SF6 gas

    Aug 23, 2010Emissions of SF6 gas from switchgear contribute significantly to the threat of the greenhouse effect and associated climate change. SF6 is on the list of greenhouse gases in the Kyoto Protocol (1). SF6 is the most potent of the six main greenhouse gases, with a GWP of 23,000 (5).
