Reactor
A reactor, also known as an inductor, is a component that converts electrical energy into magnetic energy for storage.
Possessing a certain inductance, it restricts sudden changes in line current.
It is mainly used to limit short-circuit current, suppress inrush current during capacitor switching, and attenuate high-order harmonics in power systems.

Suppress waveform distortion
Input reactors are used to limit current shocks caused by sudden grid voltage changes and switching overvoltages.
They also filter harmonics to suppress distortion of the grid voltage waveform.

Support for large-scale flexible production
01
Support for large-scale flexible production
Relying on fully automatic winding systems, precise tension control and vacuum impregnation processes, we achieve efficient, large-scale production of various reactors ranging from low-voltage filtering to high-voltage smoothing. The production line supports rapid model changeover, flexibly meeting diverse and customized delivery requirements for new energy power generation (PV/wind power), electric vehicle charging, industrial frequency conversion, power quality management and other applications.

03
Full-process performance and reliability verification system
We have established a full-chain testing and quality control system covering everything from magnetic core material properties and wire insulation class, to finished product electrical performance (L‑I curve, loss, temperature rise, withstand voltage, insulation resistance), mechanical characteristics (noise, vibration) and environmental durability (damp‑heat cycling, thermal shock). This ensures stable performance, safety and reliability of products throughout their full life cycle.
