sf6 Gas Mixture Regeneration System

sf6 Gas Mixture Regeneration System

SF6 gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.

  • SF6 gas recovery regeneration | Brizio Basi

    The sulfur hexafluoride gas simply called SF6 is used as a dielectric in high voltage circuits, it must be recovered after or during its use, the BRIZIO BASI technology makes it possible to regenerate, dehumidify and filter the gas so that it can be recovered in cylinders in liquid or gaseous form. The filled cylinders can be reused again to fill new sealed circuits / switches.
