Product Description
Air Insulated Switchgear (AIS) uses ambient air as the primary insulation medium for electrical components in medium-voltage (1-52 kV) power distribution networks. Unlike SF6 gas-insulated systems, AIS eliminates potent greenhouse gases, slashing carbon footprints while delivering robust performance. Its modular, open-design construction ensures easy maintenance, compliance with global decarbonization mandates (e.g., EU F-gas bans), and resilience in harsh environments.
