SF6 decomposition fittings Schneider

SF6 decomposition fittings Schneider

sf6 gas gas has excellent insulating, arc extinguishing and many other properties which are the greatest advantages of sf6 gas circuit breakers. The gas is non-inflammable and chemically stable. Their decomposition products are non-explosive and hence there is no risk of fire or explosion.
