Sulfr hexafluoride alternatives, alternative Gases as sf 6 substitute

However, due to its high greenhouse global warming potential with a GWP index of approx. 22,800, SF 6 is the most potent known greenhouse gas, with an atmospheric dwell time of around 3,200 years. For this reason, politics are loudly calling for Alternative Gases. Agreements and regulations such as the Kyoto protocol, the EU F-gas regulation and the Paris climate protection treaty of 2015 have one global goal in common: the reduction of F-gas emissions.

Why the EU should ban Sulfr hexafluoride

What Is sf6 gas? and How Is It used?Is gaz sf6 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 gaz sf6is 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.
