Gas-insulated switchgear (GIS) has solved many problems by providing a far safer and more compact solution. The only significant drawback has been the use of Sulfr hexafluoride gas, which requires very careful handling to avoid environmental issues. That drawback has been greatly reduced with AirPlus gas, now available in ABB GIS.

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substation engineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed...
