sf 6 MV switchgear equipment

SF6 gas in switchgear SF 6 was discovered around the turn of the twentieth century and, by the 1950s, the electric power industry in the USA widely praised SF 6 as a highly favourable gaseous dielectric medium in high and medium-voltage circuit breakers, switchgear, gas-insulated substations, and other electrical equipment.

  • 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.
