MV switchgear historically uses sulphur hexafluoride (SF6), a synthetic insulating gas that enables compact and safe power systems. Yet, the impact on the planet is massive: 1 kg of SF6 is 25 t of CO2 equivalent. More sustainable power grids require a climate-friendly and future-orientated alternative. The AirSeT MV switchgear uses pure air as the insulating gas of the future (GWP = 0).
