Low Voltage Shunt Reactors

Compensate for your capacitive reactive power, keep your system balanced, and your bills in check.

High-Precision Capacitive Compensation: LV Shunt Reactors

LTECPower is a Sino-German company with over 20 years of experience in modern power systems. We design and manufacture low-voltage shunt reactors to solve your grid system problems by safely absorbing excess power, keeping your voltage stable, your power factor in check, and your bills under control.

We also own our supply chain, from core materials to final assembly, to deliver you the high‑performance, cost‑effective solutions. Built to your specs, not pulled from a catalog, LTECPower low-voltage shunt reactors can help protect your power system from capacitive overvoltages, ensuring low losses and quiet operation.

Providing solutions for the specific charging currents of underground cables and high-rise building infrastructure, we help EPC contractors and system integrators with high-performance, cost-effective power solutions. With high linearity and thermal stability, our reactors are ideal for voltage regulation in all distribution networks, tunnels, and large commercial complexes.

Eliminating Voltage Spikes in Long Tunnel & Underground Cables

Eliminating Voltage Spikes in Long Tunnel & Underground Cables

Long cables induce large charging currents, resulting in a voltage spike at the circuit’s end that can trip your equipment and shorten insulation life. LTECPower’s low-voltage shunt reactors can stop this at the source. By absorbing the excess capacitive charge before it becomes a problem, our LV shunt reactors keep your tunnel lighting, urban distribution networks, and underground cables running safely and reliably.

Correcting Leading Power Factor in Data Centers & High-Rise Buildings

Correcting Leading Power Factor in Data Centers & High-Rise Buildings

Data centers and high-rise buildings are packed with cables, UPS systems, and electronic loads, and that may push your power factor into the “leading” zone. LTECPower’s LV shunt reactors provide the inductance your system needs, and bring your power factor back to near 1.0. They are low-noise, low-heat, and easy to integrate with your existing PFC system.

Stabilizing Voltage for Distributed Renewable Energy Systems

Stabilizing Voltage for Distributed Renewable Energy Systems

Long interconnection lines and inverter resources from your solar and wind power system often generate excess capacitive reactive power, pushing your voltage too high and putting your grid compliance at risk. However, LTECPower shunt reactors act as a steadying hand. Absorbing that excess power, the shunt reactors protect your renewable assets and downstream equipment from continuous fluctuations.

LTECPower LV shunt reactors absorb excess reactive power to ensure your critical systems operate within safe voltage ranges around the clock.

Why Is the Voltage Rising at the End of My Lightly Loaded Cable Line?

Line capacitance can push the voltage at the far end higher than the source. To solve this problem, you can choose an LTECPower low-voltage shunt reactor to safely absorb that excess capacitive power, and keep your voltage stable and your equipment protected.

 It comes down to where you are installing it. Iron-core reactors are compact with good magnetic shielding, making them ideal for indoor environments like substations or distribution rooms. However, air-core reactors never saturate, making them better for outdoor, high‑voltage applications. If you are not sure which type fits your site, we can help you choose.

Generally, it depends on the type, length, and configuration of your cable system. The reactive power (kVAR)  you need should match the charging current your cables generate. Send us your cable specs, and our engineering teams can help you with a customized calculation.

Sure. In systems with fluctuating loads, capacitor banks are generally used to handle inductive loads. Our shunt reactors take over when the load drops, absorbing the excess voltage that capacitors can’t handle.

Absolutely. Our shunt reactors are designed to meet or exceed the same electrical specifications as major global brands and are fully compliant with IEC and IEEE standards.
