    Apr 19, 2018 · At this year’s Hanover Fair, ABB is displaying an innovative and climate-friendly version of the RMU, the SafeRing AirPlus. Instead of the traditionally used SF 6 (sulfur hexafluoride) gas, this eco-efficient gas-insulated switchgear (GIS) makes use of the new AirPlus™ insulation gas. The SafeRing AirPlus has the same compact dimensions as the standard Sulfr hexafluoride-version, but reduces the global warming potential (GWP) of the insulation gas by over 99.99 percent.
