  • Help combat climate change with SF6-free MV switchgear

    Feb 10, 2021The F-gases include SF 6 – or sulphur hexafluoride – that has a global warming potential of around 23,500 times greater than carbon dioxide. SF 6 is still used by many manufacturers as an insulator and switching medium in MV switchgear. Globally, the energy industry utilises 80% of the SF 6-gas that is manufactured.

  • ALTERNATIVE GAS INSULATION IN MEDIUM-VOLTAGE SWITCHGEAR

    SF6 is used as insulation gas in gas-insulated switchgear (GIS) today since the technical performance of SF6 perfectly matches to the technical requirements. The drawback of SF6 is the high global warming potential (GWP) of about 23.500 (100 year time horizon, CO2 equivalent) which is subject to discussion in the EU and in other countries. Several gases and gas mixtures have been analysed in

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 20203. 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.

    We estimate the banked SF6 volume in MV switchgear for EU28 today with 8600 t. This is equivalent to about 20% of the yearly greenhouse gas emissions of the EU28 power generation industry. The yearly operation emissions are 0.1% of the banked volume. Impact assessment of F-gas free medium voltage switchgear
