Air insulated switchgear | SF₆-free | Eaton

SF₆-free alternatives exist in the market, such as vacuum technology that Eaton pioneered 60 years ago. This isn’t a new technology. For example, Eaton’s Xiria ring main unit was launched in 2002 and over 100,000 units have been sold since then, proving the markettrust in SF 6-free technology. Using vacuum as the switching medium and solid epoxy resin for the insulation, the equipment is as compact or more compact than equivalent gas-insulated alternatives.Get price
