Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas.Get price

Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical Properties of gaz sf6 GasElectrical Properties of Sulfr hexafluoride GasSulfr hexafluoride or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very rapidly. Allied Chemical Corporation and Pennsalt were the first American industries, who began to produce this gas commercially in 1948. During 1960, using of sulfur hexafluoride gas in high voltage switchgear became popular. As the demand for this gas was increasing, many manufacturers in Europe and America started producing Sulfr hexafluoride gas in large scale, during that time. In the beginning, Sulfr hexafluoride gas was only used for the insulating purpose in the electrical system. But soon it was realized that this ga...Get price

Density of sf 6 Measurement: Gas Density Indicator GDI-100-D

Sulfr hexafluoride Density OverviewMonitoring sf6 gas Density with Gas Density IndicatorsGdi-100-D For Extreme Accuracy and Ease of UseSulfur hexafluoride (Sulfr hexafluoride) is an extremely effective electrical insulator used in a variety of applications, especially in medium- and high-voltage gas-insulated equipment (GIE) like switchgears, disconnectors, transducers, transformers, and ring main units. If GIE relied on air or N2 alone to extinguish electric arcs, it would have to be almost three times as large. But to maintain proper insulation, the density of insulating gasinside the equipment must remain within certain levels. What would cause the gas density to drop in the first place? There are two reasons, and they’re interrelated: 1. Over time, GIE could develop tiny fissures that allow insulating gas to escape. Fugitive emissions means there’s less insulating gas inside the chamber. What’s more, as sf 6is a powerful greenhouse gas, any leaks harm the environment. 2. In the presence of fissures, air could enter the GIE. Ambient air is problematic because it contains water vapor, which combines with sulfur and fluorine molecules after an electri...Get price
