  • Manual for installation and operation HB 605/04 en

    2018-5-10sulphur hexafluoride (SF 6) SF 6 is an inorganic chemical compound of the elements sulphur and fluorine. It is a non-toxic, colourless and odourless inert gas. As SF 6 is heavier than air it displaces the oxygen in the air if it is inadvertently set free. The dielectric strength of SF 6 is 2.5 times that of air.
