  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

    Early RepublicThe Mexican WarCivil WarSpanish-American WarWorld War IInterwar YearsWorld War IIKorean WarReorganization and VietnamPost-Vietnam DevelopmentsIn the first half of the 19th Century, the Ordnance Department played a crucial role in the burgeoning Industrial Revolution and helped to establish the “American System of Manufacturing”. One of the most significant achievements was the establishment of two federal armories; Springfield Armory in 1795 and Harpers Ferry in 1798. Per congressional direction from 1794, each armory staffed a civilian superintendant and a master armorer. These two armories served as a nucleus for technological innovation for the young republic. Inventors such as Eli Whitney and Simeon North developed the methods and means for mass production through interchangeable parts and refined technology in milling machinery. By the dawn of the War of 1812, the Secretary of War recognized the need for a distinct branch to manage the procurement, research, and maintenance of Ordnance materiel.

  • Why the EU should ban sf6 gas

    What Is sf 6? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf6 gas Emissions Difficult? Do Better Solutions Exist?Conclusionsf6 gas 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.
