Air-Insulated Switchgear (AIS) is a widely used electrical power distribution solution for medium and high-voltage applications (up to 1,200 kV). Unlike Gas-Insulated Switchgear (GIS), AIS relies on ambient air for insulation, making it a cost-effective, simple, and easily maintainable choice for outdoor and large-scale installations.
✔ Simple & Robust Design – Uses air as a natural insulating medium, reducing complexity.
✔ Lower Initial Cost – More economical than GIS for high-voltage applications.
✔ Easy Maintenance & Expansion – Open design allows quick inspection and modification.
✔ Suitable for Large Substations – Ideal for high-capacity power transmission in open spaces.
