FAQ
Learn more about Air Circuit Breakers through these frequently asked questions.
AIS is substation equipment that uses ambient air at atmospheric pressure as the primary insulating medium between live components. It is known for its open, robust, and highly reliable design.
Primarily for its low Total Cost of Ownership (TCO), simplified maintenance, and strong environmental profile (with no bulk SF₆ insulation).
Yes. Using ambient air as the main insulator means the system has zero greenhouse gas potential related to the insulation medium, aligning with strict green regulations.
The main components include the Circuit Breaker (CB), Disconnectors/Isolators, Earthing Switches, and Instrument Transformers (CTs/VTs).
It requires routine visual inspections, cleaning of insulators, and scheduled overhaul/testing of the circuit breaker mechanism every 5-10 years.
With proper maintenance, the operational lifespan is typically 30 to 50 years due to its robust, modular design.
AIS is versatile, suitable for a wide range from Medium Voltage (MV) up to Ultra-High Voltage (UHV) (e.g., 550 kV and 800 kV) applications
Systems must comply with international standards such as the IEC 62271 series or the IEEE C37 series.
Installation is generally simpler and faster than GIS, as it requires less specialized equipment, minimal on-site gas handling, and uses standardized assembly techniques.
The open design offers maximum visibility for quick inspection and easy access to all components, simplifying maintenance and troubleshooting compared to fully enclosed systems.
