  • SF6 gas in medium-voltage switchgear | TD - Siemens USA

    The process is reversible, so that nearly all of the SF6 recombines after interruption. Thus, very little of the SF6 is used up during interruption, particularly for interruption of moderate (load) currents. SF6 dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.
