Eco-efficient alternatives to insulating gas: Continuing the AirPlus

May 30, 2019 · At CIRED 2019, the world’s most important conference for medium-voltage technologies in distribution grids, ABB continues the success story of its eco-efficient insulation gases. ABB’s AirPlus™ technology is a revolutionary technology from ABB, and an alternative to sulfur hexafluoride (SF 6) gas. Four years ago, at CIRED 2015 in Lyon, France, ABB announced the world’s first eco-efficient AirPlus switchgear at the Oerlikon substation of Swiss utility ewz.
