  • SF6 Gas – Professional SF6 gas handling equipment and

    SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Due to its first-class properties it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas. Since SF 6 is a major greenhouse gas with high global warming potential listed in the Kyoto protocol, it is among the six gases subject to monitoring.
