Magnetic Circuit Optimization
15% Overvoltage Linear Safety
Traditional solid-core reactors are prone to overheating and failure during voltage spikes. Engineered with CRGO gapped-core, our shunt reactors have no magnetic saturation even under grid fluctuations.
Whisper-Quiet and Vibration-Free Operation
With precision ceramic air gaps and a rigid clamping structure, our reactor’s core is firmly locked in place, ensuring you less hum, less stress on enclosures, and a quieter, more comfortable environment.
For Compact Switchgear Integration
Space means money in modern electrical rooms. Built with optimized magnetic circuits and a rigid non‑deforming core layout, our shunt reactors ensure you minimal structural heat losses.
Copper and Aluminum Customization
Every project is different. To respect that, we offer you a flexible coil made of 100% pure aluminum to support your strict cost control and balance your budget.
No Hot Spots
To eliminate the hidden risk of localized, dangerous heat, our shunt reactors are engineered with internal conductors at calculated intervals, ensuring a perfectly uniform current distribution.
Precision-Brazed Joints
Using natural vertical cooling ducts, our coils can breathe freely without noisy external fans. And a precision-brazed connection, so your power network stays uninterrupted for decades without vibration fatigue.
Insulation and Transient Resilience

Common Applications of Shunt Reactors
Industrial Power Factor Correction (PFC) and Managed Infrastructure
For factories with dense underground cables, our shunt reactor automatically absorbs dangerous parasitic capacitance, keeping your grid perfectly stable 24/7, every single night.
Connected with your detuned filters, the reactor blocks excessive current stress and prevents premature degradation and unexpected downtime.
With low-loss, high-linearity design, our shunt reactors are built for sustainable savings. Minimizing heat dissipation, they ensure you a smart, sustainable investment.
Urban Mass Transit and Electrified Transportation Hubs
Built for heavy-duty rail transit, our shunt reactors guard your metro grid.
Dynamically balancing mid-night cable capacitance with mechanical strength, they can prevent insulation burnout, surviving violent transit short-circuit shocks with whisper-quiet operation.
So your municipal communities are completely undisturbed.
Heavy Industrial Power Quality and Telecommunication Hubs
Engineered for high-capacity UPS and data centers, our shunt reactors can protect your servers and profits.
Acting as a smart purifier to neutralize network distortion during light-load server idle hours, they can eliminate your utility penalties and shield your fragile digital infrastructure from unexpected voltage surges.
So your data center can run safely and 100% uninterrupted.

Absorbing capacitive reactive power (VARs) and avoiding dangerous voltage spikes.
Long underground cables and lightly loaded transmission circuits generate capacitive reactive power, which leads to a voltage rise.
Our shunt reactors provide immediate inductive counterbalancing and prevent terminal voltage rise. So you can get a stable voltage profile within the standard 0.95 to 1.05 p.u.
Engineered for low- and medium-voltage networks, our shunt reactors are your reliable shield. Built with precision-bonded ceramic air gaps, they can keep your performance perfectly stable up to 115% voltage spikes.
Before dangerous harmonic pollution starts, our reactors prevent your early core saturation. So your critical systems are safe from unexpected power surges.
Both of them are tailored solutions for your grid.
Shunt Reactors: Connected in parallel to absorb excess cable capacitance, shunt reactors can stabilize your midnight voltages.
Filter Reactors: Connected in series to safeguard your sensitive PFC capacitors from destructive resonance, filter reactors can keep your system safe, balanced, and worry-free 24/7.
Precision matching is crucial for reactors. Because a tiny shift in reactor tolerance may trigger destructive harmonic resonance. Your capacitor banks may lead to sudden burnout.
Built with strict, flawless inductance precision, every one of our reactor units can lock the safety frequency your system needs. Preventing thermal risks, they also keep your cabinet panel safe day after day.
The electromagnetic vibration loosens joints and disturbs nearby electronics.
