The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling

The alternative C5-fluoroketone/air gas mixture coines good electrical features and a reduction of the global warming potential by nearly 100% compared to SF6 and does not require any additional special handling. The new alternative gas will be introduced stepwise into ABB’s current gas insulated switchgear platform as an alternative to SF6

Azeotrope - Wikipedia

An azeotrope (/ ə ˈ z iː ə ˌ t r oʊ p /) or a constant boiling point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
