High-Efficiency Three-phase Silicon Steel Inductor

A three-phase silicon steel reactor is a three-phase AC power device that utilizes silicon steel laminations as its core material. It plays a vital role in power systems by limiting currents, suppressing harmonics, and improving power quality.

  • Product Description

High-Efficiency Three-phase Silicon Steel Inductor

 

Built with a high-performance silicon steel core, this three-phase inductor is engineered to deliver efficient power conversion, stable current control, and reliable filtering performance. Its optimized magnetic structure helps reduce energy loss while maintaining excellent thermal stability during long-term operation. Suitable for industrial power equipment, renewable energy systems, motor control applications, and other three-phase power solutions, it ensures smooth operation and improved system efficiency.

 

 

Key Features

Input/Line Reactor: Placed between the supply and VFDs. Limits inrush currents from grid transients, protects the drive, and reduces grid-side harmonics while improving power factor.

Output Reactor: Placed between the VFD and motor. Compensates for long-cable capacitance effects, suppresses output harmonics, and shields motor insulation from voltage spikes.

Series/Tuning Reactor: In series with power capacitors for harmonic filtering. Absorbs specific harmonics (e.g., 5th, 7th) and suppresses capacitor-switching inrush currents to protect capacitor banks.
