    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.cart
