SF6-alternatives system Draeger

Aug 23, 2010 · 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.

  • An alternative to SF6 in electrical switchgear - EE Publishers

    For decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. However, SF6 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 […]
