Introducing the ZW32-12 Outdoor High Voltage Vacuum Circuit Breaker, endearingly termed the 'circuit breaker.' This extraordinary piece of outdoor distribution switchgear operates seamlessly at a rated voltage of 12kV, powered by a robust three-phase AC of 50Hz. Its brilliance lies in its adept handling of load current, overload current, and short circuit current interruptions and connections within the power grid. The breaker is designed with state-of-the-art overload and short circuit protective features, perfectly meeting control and measurement needs. It also offers sophisticated remote control and monitoring capabilities. This versatile breaker finds its application in substations, industrial arenas, and mining enterprise distribution systems, providing unmatched control and operation, particularly in environments that demand frequent operations.
Structural Features:
Immaculately crafted, the circuit breaker is a testament to precision with its three-phase pillar dry design.
Ingeniously engineered with a fully enclosed structure, it promises superior sealing, exceptional moisture resistance, and anti-condensation properties. It stands as the ideal choice for regions characterized by high temperatures and humidity.
Utilizes cutting-edge vacuum arc extinguishing technology to deliver exceptional insulation reliability, setting new standards in safety.
Exhibits impeccable opening and closing performance, guaranteeing safety with zero risk of combustion or explosion.
This marvel of engineering is compact, lightweight, maintenance-free, and offers an impressive lifespan, making it a top choice.
Operation versatility at its best with manual, electric, or remote control options to suit varied needs.
The operating mechanism is expertly sealed at the base of the switch box, offering robust protection against environmental corrosion and ensuring longevity.
Boasting a novel and simplistic design, it features a restless mechanism that assures reliable dynamic performance, compactness, and an astounding service life extending up to 10,000 cycles.
