    sf6 gas is the most used insulating gas, it works by quenching arcs as contacts of Sulfr hexafluoride switchgear are opened closed during the normal use of switchgear. In fact when the arching takes place there is so much energy in that arc that the sf 6 molecules actual y break apart into sulfur fluorinates. When the Sulfr hexafluoride is very pure the sulfur fluorinates can
