Overview

ZW32-12(G) Series Outdoor High-Voltage Vacuum Circuit Breaker, hereinafter referred to as the "breaker," is an outdoor distribution switchgear designed for a rated voltage of 12kV and a three-phase AC frequency of 50Hz. The breaker is primarily used for opening and closing load currents, overload currents, and short-circuit currents in power lines, featuring overload and short-circuit protection functions, meeting control and measurement requirements. It also enables remote control and monitoring capabilities, widely applied in substation and industrial and mining enterprise power distribution systems for control and operation purposes, particularly suitable for frequently operated sites. The breaker complies with technical standards such as C81984-2003, DUT 402-2007, and IEC60056.

Structural Features

◆Overall structure is a three-phase pillar type dry-type structure:

The product features a fully enclosed structure with excellent sealing performance, providing good moisture and condensation resistance, suitable for use in high-temperature and humid areas.

Vacuum arc extinction, reliable insulation:

◆ Reliable open and close performance, no risk of combustion or explosion.

Small in size, lightweight, maintenance-free, with a long service life:

Operation of opening and closing switches can be manual, electric, or remote-controlled.

The actuating mechanism is sealed at the bottom of the switch box, effectively preventing rust caused by long-term outdoor exposure.

◆ The actuating mechanism is designed innovatively with a simple structure, reliable operation, compact size, and a lifespan of up to 1,000 cycles.
