  • SF6 Gas Insulated Substation - SF6 Ring Main Unit

    The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 years.

  • nycsubway.org: SEPTA Broad Street Subway

    OverviewStation by StationRosterPhotos by LocationRelated DocumentsLinksThe idea for a Broad Street subway line dates back to 1912 when Philadelphia appointed A. Merritt Taylor to study transit expansion in the city. Among the options he came up with were the Broad Street line and what became the Ridge Avenue Spur. Typical to big cities the ideas were studied, restudied and then changed and the process repeated. The general arrangement of the as-built Broad Street Subway is a two and four track subway underneath Broad Street for its entire length, and a spur running southeasterly from Fairmount and Broad Streets. The spur runs underneath Ridge Avenue to 8th Street, where there is a grade separated junction, with tracks leading easterly to the Ben Franklin Bridge and south along 8th Street to Locust Street. At Locust the spur turns westerly to 15th/16th Street. The Ridge Spur was to have been part of a Center City loop. On the main line, flying junctions were built at Erie, Olney, and Snyder for future extensions. Dirt is moved beginning in 1924, with th...

  • 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
