GIS is a compact, metal-enclosed switchgear in which the live parts are insulated with a gas (SF6 or an SF6-free gas) instead of air, allowing a much smaller footprint and higher reliability, typically for high-voltage substations.
AIS (air insulated) uses air as the main insulation with a large footprint; GIS uses a gas with high dielectric strength, reducing footprint by up to 80-90% and improving reliability in harsh or space-limited environments.
Hybrid GIS combines gas-insulated and air-insulated technologies in one bay — using gas-insulated components for the switching parts and air terminations for busbars and lines — optimising cost and footprint.
Yes. We supply SF6-free gas insulated switchgear for secondary distribution and SF6-free dead tank circuit breakers, supporting low-GWP, environmentally friendly alternatives.
Yes. The GIS portfolio is engineered to IEC 62271-203 (GIS) and IEC 62271-100 (circuit breakers), with ratings independently verified.
