    What Is sf 6? 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 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 sf 6produced (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.

  • Background Reference: Iran - Energy Information Administration

    OverviewManagement of Oil and Natural Gas SectorsNatural GasElectricityEndnotesIran holds some of the world’s largest proved crude oil reserves and natural gas reserves. Despite its abundant reserves, Iran’s crude oil production has undergone years of underinvestment and effects of international sanctions. Despite Iran’s abundant reserves, crude oil production stagnated and even declined between 2012 and 2016 as nuclear–related international sanctions that targeted Iran’s oil exports hindered progress across Iran’s energy sector, which affected upstream investment in both oil and natural gas projects. At the end of 2011, the United States and the European Union (EU) imposed sanctions as a result of Iran’s nuclear activities, which went into effect in mid–2012. These sanctions targeted the Iranian energy sector and impeded Iran’s ability to sell oil, resulting in a near 1.0 drop in crude oil and condensate exports in 2012 compared with the previous year. After the oil sector and banking sanctions were lifted, as outlined in the Joint Comprehensive Plan of Actio...
