China Outdoor High Voltage SF6 Gas Circuit Breaker Manufacturers, Suppliers, Factory

Lugao is a 220KV Current Transformer Electric Substation Equipment manufacturer with 15 years of professional experience. As a China Famous Trademark, our products exemplify quality. Our voltage transformer earned global acclaim, exported to over 30 countries and regions, showcasing our commitment to excellence.

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 stands as a dedicated 15KV Indoor Type Disconnector Switch manufacturer.GN22-12(C) disconnector is an indoor high-voltage switchgear designed for use in power systems with three-phase AC 50Hz and a rated voltage of 12kV. Its primary function is to connect, disconnect, or switch lines under voltage conditions when there is no load on the equipment.
