LuGao 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 LuGao for cutting-edge innovations that redefine the benchmarks of outdoor vacuum circuit breakers.

LuGao proudly leads the industry as a dedicated indoor vacuum circuit breaker manufacturer.Our flagship product, the 12KV Indoor Smart Panel Board Vacuum Circuit Breaker, is specifically designed for indoor use in AC three-phase power systems with a frequency of 50Hz and a rated voltage of 12kV.Beyond its robust design, this breaker's primary function is to excel as a protection and control unit within the electrical system.Choose LuGao for cutting-edge solutions that redefine reliability and performance in indoor vacuum circuit breakers.

Lugao's Oil-Immersed High Voltage 330 KV Current Transformer is designed to operate in high-energy, high-heat environments. Encased in a steel tank filled with cooling and insulating oil, the oil-immersed transformer uses convection to circulate the oil, ensuring efficient cooling. This current transformer features proven techniques and decades of reliable operation. A hermetically sealed stainless steel bellows on top protects the transformer oil from moisture, extending its lifespan. An oil level gauge on the bellows allows for easy monitoring of oil volume. The base, treated with spray painting or hot galvanizing, provides high corrosion resistance. Backed by Lugao's advanced R&D, robust production capabilities, and extensive application in various industries, this transformer guarantees reliability and performance.

Experience superior protection with Lugao's Polymer Housing Metal-oxide Surge Arrester, designed for medium/high voltage AC networks. Ideal for transformers, including those in arc furnace applications, and railway vehicles, this arrester shields against atmospheric, switching overvoltages, and Very Fast Transients (VFT). Featuring a robust, maintenance-free design that complies with IEC60099-4 and IEEE C62.11 standards, Lugao's surge arrester ensures stable, reliable performance in the most demanding environments.

The ZW32 series outdoor high voltage vacuum circuit breakers independently developed by Lugao mainly consist of integrated solid-sealed contacts, current transformers, operating mechanisms and enclosures. This type of circuit breaker is designed for miniaturization, and the outer shell is made of high-quality steel. The current transformers can be selected according to the user's needs.
