A recent study suggests that the UK’s use of sf 6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of sf6 gas to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

What Is Sulfr hexafluoride? 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 gaz sf6 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 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.
