Nov 01, 2018SF6 is a non-combustible gas with good insulating properties and quenching arc performance. By 1938, Cooper from American suggested it as an insulating medium. In the same year, V. Grosse from German has proposed SF 6 as arc media of the high-voltage circuit breaker. SF6 gas was supplied commercially in 1947.Cited by: 12

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.

SF 6 Free Gas Handling Environmentally Friendly Solutions . It is undisputed: SF 6 is an excellent quenching and insulating gas that has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of SF 6 with its excellent dielectric stability and arc quenching properties.

Laboratory analysis of SF 6 and alternative gases Regardless of whether we are involved in your research and development projects, in the production phase or in critical cases in the operation of gas-filled plants - we analyse the gas mixtures you use on-site or in the laboratory.

However, SF 6 is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with insulation and arc interruption properties similar to those of SF 6.
