Engineered for 12kV, 50Hz systems, the FKN12-12 and FKRN12-12D provide precise three-phase switching for load and loop currents. The FKRN12-12D integrates a fuse to interrupt short-circuits, offering verified protection for distribution stations and industrial equipment in ring network scenarios.
Engineered for 12kV, 3-phase AC 50Hz systems, the FN7-12DR Indoor High-Voltage Load Switch reliably handles load and short-circuit currents. As a combined apparatus, it provides comprehensive protection against all current faults. Compliant with IEC standards, its compact and user-friendly design makes it an ideal core switching solution for industrial and commercial indoor power distribution.
The FKW18 Series Outdoor High-Voltage Load Break Switch integrates domestic expertise with global technology. Designed for 40.5kV, 50Hz three-phase AC systems, it features an isolation knife and a gas-generation arc-quenching chamber. This design ensures superior arc extinction, high insulation, and reliable performance with minimal maintenance.Capable of safely switching both loaded and no-load lines, the FKW18 provides a visible isolation gap in the open position that meets standard disconnect
The FZN25 and FZRN25 Series are engineered for 50Hz AC ring networks and industrial systems. The FZN25 vacuum load switch handles load, closed-loop, and cable charging currents, while the FZRN25 combined apparatus provides robust short-circuit protection up to rated fault levels.Featuring a specialized transmission design, the arc-extinguishing chamber only withstands voltage during switching, ensuring a compact, lightweight build with seamless one-step operation. Equipped with manual and electr
The FZN21-40 Series Indoor AC High-Voltage Load Switches and Fuse Combination Units are engineered for 40kV, 50Hz three-phase power systems. Designed for versatile integration with complete power distribution equipment, ring-network switch cabinets, and combined substations, these units are widely deployed in urban grid projects, industrial facilities, high-rise buildings, and public infrastructure as reliable ring power or terminal equipment for power distribution, control, and protection.
