  • Transmission System Substation Refurbishment |

    12 mins readMay 20, 2016The GIS substation can be built and almost fully commissioned before any circuit outage is required. Therefore, the installation and commissioning costs are lower than that of the partial upgrade approach. Replacement of several substations at the same time can include design savings by standardizing layouts and electrical designs.

  • SF6 (GIS) gas insulated substation Manufacturer in China

    Space needed for GIS substation layout is less than 20 percent of AIS. Maintenance. The rate of malfunction of disconnecting circuit breaker and switch in GIS is ¼ of that of air-insulated substation, and 1/10 when it comes to the busbar. Therefore, the maintenance expense of a gas-insulated becomes less than that of air insulated for a lifetime.
