Electrical Axis· This gas is stable up to 500 degrees C. SF6 gas is inert which make it advantageous for switchgear applications. Thus, the life of metallic part, contacts is longer in SF6 gas because the components do not get oxidized or deteriorated. SF6 is an electron negative gas which can easily arrest electrons from the arc.
