Switchgear - Environment first with SF6· The advantages of using SF6 in HV switchgear are considerable, not least because the gas is non-flammable, non-corrosive to internal switchgear components and its thermal properties make it an exceptional arc suppressant: even when SF6 is momentarily broken down during arcing, it largely re-combines back into its original state.
