    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.

  • Green Switching: A sustainable alternative for SF6 gas

    Aug 23, 2010SWITCHGEAR WITH SF6 GAS There are three principal designs for SF6-insulated switchgear. With the first two, known as controlled pressure systems and closed pressure systems, release of SF6 is unavoidable in practice. This is because the systems require maintenance in the course of their service life, at which point leakage occurs.
