The AGL‑126 outdoor high‑voltage AC sulfur hexafluoride circuit breaker (hereinafter referred to as the “circuit breaker”) is an outdoor‑mounted, three‑pole, 50 Hz AC high‑voltage switchgear that uses SF₆ gas as both the arc‑extinguishing and insulating medium. It can be used to make and break rated currents and fault currents, switch capacitor banks, and transfer circuits; it may also serve as a tie‑breaker, providing control and protection for transmission and distribution lines and associated equipment. It is particularly well suited for frequent operations and is equipped with a CT20 spring‑operated mechanism.
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.
