Overview

? The ZW20-12 outdoor column mounted vacuum circuit breaker is a three-phase AC 50Hz, 10kV outdoor high-voltage switchgear mainly used in medium voltage overhead power grids, as well as in industrial and mining enterprises, power plants, and substations. It is used for breaking and closing load currents, overload currents, and short-circuit currents. This product adopts vacuum arc extinguishing method and SF6 gas insulation. The insulation sleeve of the incoming and outgoing lines is integrally cast with epoxy resin and silicone rubber. To reduce the switch volume, corner sleeves are used for phase A and C to ensure good external insulation.
