  • Transmission System Substation Refurbishment | TD World

    GIS has all of the same components as AIS (such as busbar and disconnectors). However, as GIS is insulated by sulfur-hexafluoride gas (SF 6) and fully enclosed, the footprint of a GIS substation is only a fraction of that of the equivalent AIS substation. GIS building locations were chosen to minimize high-voltage cable lengths and ensure adequate space would be available for any future expansion or
