3U HV Reactors
The 3U High-Voltage Reactor is designed for power systems below 35 kV and used in series with power capacitors to form tuned filter branches. It suppresses harmonic currents, prevents capacitor overload and overvoltage, and improves the reliability and service life of reactive power compensation systems.
Product Description
The 3U series adopts a three-phase integrated dry-type iron core structure with foil winding technology. The low-loss silicon steel core, vacuum impregnation, and epoxy resin coating provide low noise, strong insulation, and reliable operation under demanding conditions.
