12KV Ring Main Unit Switchgear Panel manufactured by Liugao.The HXGN15-12 metal-clad ring main unit switchgear, of the intelligent type, is designed for application in a three-phase AC system with a rated voltage of 12kV, a rated frequency of 50Hz, and a rated current of 630A.It serves the purpose of ring network electricity supply and radiation terminal power supply, particularly in cable line sectionalizing and branch connection scenarios.The switchgear is equipped with an SF6 gas insulating multiloop power unit and a feeder terminal device (FTU) imported from Korea.Notably, it features advanced functions such as remote signaling, telemetry, remote control, and fault current detection.Primarily utilized as a distribution automation system, it proves beneficial for city power supply load centers and cable supply applications.

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.
