  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • SF6 gas handling - DILO

    What are the most important factors of quality criteria for SF 6 gas in gas insulated switchgear (GIS)?. The following is of great importance: gas density, moisture concentration, decomposition products, gas purity (air concentration) which are determined by means of special SF 6 measuring instruments as well as gas density controllers. DILO supplies the measuring devices required for the

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring 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.

  • Measurement of the ionisation and attachment

    Here €is the electric field,pzO is the gas pressure at 20 C and Nis the gas number density. The SF6 and air mixture is considered to be an important substitute for pure SF6 as an insulant at high voltage since, unlike the pure gas, the mixture has high dielectric strengths even in non-uniform fields.

  • Electron Transport Coefficients and Effective

    The electron drift velocity, electron energy distribution function (EEDF), density-normalized effective ionization coefficient and density-normalized longitudinal diffusion velocity are calculated in SF6-O2 and SF6-Air mixtures. The experimental results from a pulsed Townsend discharge are plotted for comparison with the numerical results. The reduced field strength varies from 40 Td to 500 Td

  • Railway density - Statistical Database - United Nations

    Railway density. Length of lines of transportation made up by rail exclusively for the use of railway vehicles and maintained for running trains divided by the geographic area of the country. A line is made up of one or more tracks. Stretches of road or water even if rolling stock is conveyed over such routes, e.g. by wagon- carrying trailers
