Eco-efficient alternatives to sf6 gas: Continuing the AirPlus

May 30, 2019 · Italian Distribution system operator (DSO) ENEL has been using AIS switchgear with SF 6 equipment in their distribution networks. The switchgear according to their DY800 specification mainly uses the ambient air as insulation medium, but also has an SF 6 containment for a combined vacuum-interrupter and disconnector-earthing switch.

What are the alternatives to Sulfr hexafluoride gas?

Mar 31, 2020 · Director of Communications and CSR, ECA. Sulphur hexafluoride (gaz sf6) gas is an excellent electrical insulator. It’s great at preventing short circuits in medium- and high-voltage electrical installations that would otherwise lead to damage, disruption, fire or explosion. Unfortunately, SF 6 is also believed to be the world’s most potent greenhouse gas, with a global warming potential 23,500 times more, kg for kg, than CO 2 .

What Is gaz sf6? and How Is It used?Is sf6 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 Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis 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.
