Schneider sf6 gas filled equipments

Because of its low dissociation temperature and high dissociation energy, SF 6 is an excellent arc quenching gas. When an electric arc cools in SF 6, it remains conductive to a relatively low temperature, thus minimising current chopping before current zero, and thereby avoiding high overvoltages.
