  • 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.

    SF 6 Free Gas Handling Alternatives to SF 6. The so-called Alternative Gases are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.

  • ALTERNATIVE GASES | DILO GmbH

    Alternative gases as SF 6 substitute Focus on the environment. SF 6 is an excellent quenching and insulating gas which has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of SF 6 with its excellent dielectric stability and good electric arc quenching properties.

  • Green Switching: A sustainable alternative for SF6 gas

    Aug 23, 2010SF6 is the most potent of the six main greenhouse gases, with a GWP of 23,000 (5). The United Nations institution that monitors this, the Intergovernmental Panel on Climate Change (IPCC), has since added SF6 gas to the list of extremely harmful greenhouse gases. The Kyoto Treaty (1992) stipulates that emissions of SF6 gas must be reduced.

  • SF6-alternative gases for application in gas-insulated

    Mar 20, 2018Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases. Recently, this effort has made important progress, with promising alternative gases being identified and tested.
