Lugao's independently developed vacuum circuit breakers have received widespread acclaim overseas. The 12kV, 24kV, 36kV HV, and MV Side-Mounted Smart Vacuum Circuit Breaker for Switchgear, rated at 12 kV and 50 Hz, is suitable for three-phase AC indoor power distribution systems. It rapidly interrupts short-circuit currents, primarily protecting electrical equipment. The VS1 circuit breaker features a compact design and is easy to install, requiring only regular inspection of the contact wear.
The 12kV, 24kV, 36kV Hv and Mv Side-Mounted Smart Vacuum Circuit Breaker for Switchgear is a core protection device in power distribution systems. It utilizes solid-pole technology to integrally cast the vacuum interrupter in epoxy resin, significantly enhancing insulation strength and pollution resistance. It also features a permanent magnetic operating mechanism for high-speed and reliable opening and closing operations. Its mainstream trolley-type structure seamlessly adapts to standard center-mounted switchgear models, such as the KYN28 and XGN models. It supports a rated current range of 630A to 3150A and interrupting current levels of 20kA to 40kA. Its compact design, maintenance-free operation, and excellent environmental adaptability make it widely applicable for the protection and control of transformers, motors, and capacitor banks in substations, industrial and mining power distribution, and large-scale building power supply scenarios.
