Reliable contact structure: spring‑pressed sliding contacts ensure self‑cleaning and self‑locking during closing, withstanding a 31.5 kA/3 s short‑circuit current; low and stable loop contact resistance. Double‑column, centrally interrupted, hot‑dip galvanized steel base; insulators are adjustable for leveling; standard 90° opening and closing stroke; excellent mechanical stability. Safety interlock: integrated hard‑mechanical interlock with the earthing switch, completely preventing erroneous live‑earth connections; available in male/female contact configurations for earthing. Universal mounting: compatible with rectangular and circular reinforced‑concrete poles; vertical drive shaft can be segmented to suit different installation heights; supports both electric and manual operating mechanisms. Easy maintenance: standardized disassembly and assembly procedures, accompanied by a comprehensive lubrication plan; three‑level periodic maintenance schedule; contacts and transmission components can be replaced individually. Complete protection: factory‑applied protective coating on conductive surfaces; optional anti‑condensation heating for the mechanism; all components resistant to outdoor weathering and corrosion.

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.
