SF6 GAS AND THE ENVIRONMENT . SF6 Advantages (1, 2) The electric power industry has been using Sulfur Hexafluoride (SF6) gas as a dielectric and insulating material for many years. Its popularity is mainly due to its unique physical and electrical properties including: 1) Dielectric strength twice that of air.
SF6 has been identified as a highly potent greenhouse gas that causes climate change. The global warming potential (GWP) of SF6 is 22,800 times higher than that of CO2. SF6 also has an atmospheric life of 3,200 years. A large percentage of the SF6 being used today is in closed system appliions.
The SF-36 has become the most widely used measure of general health in clinical studies throughout the world. It currently generates eight dimension scores and two summary scores for physical and mental health. Whilst such scores provide an excellent means for judging the effectiveness of health
Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. 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, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission
