Sulfur Hexafluoride (sf 6) Emission Estimates for China: An

Abstract. Sulfur hexafluoride (insulating gas) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, sf 6emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest Sulfr hexafluorideemission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the Sulfr hexafluorideproduction sector (each about 10%).Get price

Panel discussion: The pros and cons of using sf 6 gas in

Brighton Mwarehwa: The SF 6 gas is listed in the famous Kyoto protocol as one of the potential greenhouse gases that contribute to the global warming potential of our earth. SF 6 is always used in gas tight compartments, which greatly minimise leaks. As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes.Get price

Why the EU should ban Sulfr hexafluoride

What Is sf 6? 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?Conclusiongaz sf6 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 sf6 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.Get price
