Sf6 Gas Processing Equipments

Sulfur hexafluoride (SF₆) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF₆ has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

SF₆ was discovered by  Henri Moissan and Paul Lebeau in 1901

SF₆ is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs. SF₆ gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. This property makes it possible to significantly reduce the size of electrical gear. This makes GIS more suitable for certain purposes such as indoor placement, as opposed to air-insulated electrical gear, which takes up considerably more room.

Exposure to an arc chemically breaks down SF₆ though most of the decomposition products tend to quickly re-form SF₆, a process termed "self-healing,”

Hexa - REVAC Series is simplest solutions when only SF₆ gas filling & air evacuation from
switchgear is required. Easy to operate & a suitable with no SF₆ emission.
