  • SF6 equipment / Gas handling - Transorfilter Sweden

    Sulfur hexafluoride - SF6 is an industrially produced gas with excellent dielectric and arc quenching properties. The gas is mainly used as insulation and breaking medium in e.g. switchgear, transformers and switches for high and medium voltage. SF6-filled electronic equipment are closed systems that provide no direct emissions.
