Breadcrumb - Welcome to National Grid Group | National Grid Group

Sulphur hexafluoride (sf6 gas) sf 6 is an extremely effective electrical insulator and has significant advantages over alternative materials. It is non-flammable – a critical requirement in the high-voltage applications we use it – and because of its effectiveness takes up less volume than an equivalent insulating volume of an oil alternative.
