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.

What Is sf6 gas? and How Is It used?Is insulating gas A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all insulating gasproduced (Powell, 2002: 6). Within the electrical industry insulating gasis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
