AREVA FBARB is a fully prefabricated, outdoor, environmentally friendly gas-insulated switchgear designed for 12 kV urban distribution networks, renewable energy applications, and municipal projects. It incorporates the proven FBAIR eco‑friendly gas‑insulated switchgear units and integrates incoming feeders, ring main units, outgoing circuits, metering, and protection functions into a single compact assembly. The equipment is pre‑assembled and tested at the factory, requiring only foundation installation and cable connections on site before commissioning. Compliant with GB/T 3906 and IEC 62271 series standards, it replaces traditional civil‑engineering substations, significantly reducing the footprint while delivering robust performance in demanding outdoor conditions. It serves as a standardized outdoor distribution solution for urban cable‑based upgrades, photovoltaic and wind power integration, industrial park power distribution, and street lighting systems.
