Outdoor Vacuum Circuit Breaker (Watchdog Switch)

LiuGao proudly leads as a dedicated outdoor vacuum circuit breaker manufacturer, showcasing the Outdoor Vacuum Circuit Breaker (Watchdog Switch)—a versatile solution offering advanced functionalities. When coupled with a reclosing controller, this breaker transforms into an intelligent recloser-type breaker. In its basic mode, the breaker, paired with a reclosing controller and PT reclosing controller, forms a three-segment compound protection system. This system includes control over switch-on rush current, overcurrent protection, and short quick break. Supporting 1-3 reclosing cycles, incorporating low-current ground protection, and featuring wired supervisory control functions, it allows for remote control beneath the pole, with continuous parameter adjustments for the reclosing meter. Beyond its basic mode, the breaker excels with a three-segment compound protection system, providing control over switch-on rush current, overcurrent protection, and short quick break. Users enjoy the flexibility of continuous protection parameter regulation. This breaker stands out in both wired supervisory control and remote control under the pole, offering a comprehensive solution for diverse power distribution scenarios. Choose LiuGao for cutting-edge innovations that redefine the benchmarks of outdoor vacuum circuit breakers.

Product Description

Liugao is a Outdoor Vacuum Circuit Breaker (Watchdog Switch) supplier.The ZW32 series outdoor automatic current recloser, also known as an automatic current recloser, is designed for use in electrical power systems with a rated voltage of 12kV, 24kV, or 36kV and AC three-phase frequency of 50Hz. Its primary function is to close and break loading current, handle overloading current, and address short-circuit currents in power distribution.

This ACR is equipped with two working principles: spring and magnetic models. It offers the flexibility of manual or electrical operation, with electrical operation requiring a digital controller and PT for remote control capabilities in power transmission and distribution.

Our 12kV Outdoor Vacuum Circuit Breaker with Switchgear Protection Zw8-12g is manufactured using advanced technology and world-class manufacturing capabilities, ensuring high-quality performance and widespread applicability. Over the years, our company has adapted to the evolving needs of enterprise development and market competition, demonstrating advanced skills and prioritizing customer satisfaction. We are dedicated to delivering total quality performance with each order, and our good reputation and exceptional craftsmanship have garnered wide social acclaim.
