Dec 09, 2018 · Eaton is a leading company in power management, and has been providing medium voltage switchgear that is 100% free of gaz sf6 gas for many years. While Sulfr hexafluoride is a good insulator, it is also the worst of the global warming gases, 26,000 times worse than CO2. This is why it is banned for most uses in Europe. Eaton’s design switches in vacuum and uses solid insulation to ensure a safe, reliable, and sustainable product.Get price

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
