  • SF6 Gas handling | Zero emissions and maximum gas re-use

    SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.
