The ZCW10-126/T2000-31.5 open-type combined electrical apparatus is a complete set of combined electrical equipment that uses air for external insulation and SF₆ gas as the arc-extinguishing medium. It is used for control and protection in 126kV three-phase AC power transmission and distribution systems, and can also be applied in scenarios such as tie circuit breakers and switching capacitor banks. It is suitable for urban substations, enterprise substations, and mountain substations with limited land availability.
