    SF 6 Free Gas Handling Alternatives to SF 6. The so-called Alternative Gases are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.
