  • Vaisala electrical switchgear for Substation

    Vaisala electrical switchgear for Substation For substations where space is minimal and an integral disconnect is required, Model 2020 is an excellent solution. With its vertical-interrupter design, this model provides a low-cost means to include an integral disconnect because it uses shorter pole-unit bases and three fewer station-post insulators.

  • 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...
