  • CIGRE Articles How to reduce SF6 emissions

    SF 6 has been in use as an insulation medium since the 1960’s. It exhibits excellent properties allowing for more compact switchgear, transformers, and Gas-insulated Lines. While the lifespan is 30-50 years, SF 6 is, unfortunately, a severe green-house gas with the high global warming potential (GWP) of 22,800, relative to CO 2.It is therefore necessary to reduce emissions of SF 6.
