5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering 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-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price

Sulfr hexafluoride (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.Get price
