  • SF6 (GIS) gas insulated substation Manufacturer in China

    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.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters.

That is no longer the case. “You can load WinCan data from the field into this utility in the office,” he says. “You do not need a WinCan license or WinCan Viewer.” The software is ArcGIS 10 and 9.3 compliant and is designed to be used with dual computer screens. “It is set up for the person who maintains the GIS system,” says Russin. “CCTV data is collected on lines in the field. It comes back to the office on a hard drive or thumb drive and is loaded into the GIS.” WinCan GIS can export and integrate to most database programs, as well, including Access, SQL and Oracle. One customer of Pipeline Analytics connects the GIS data with an ArcGIS Server intranet site so that the information can be viewed online.
