Low Voltage Capacitors to Reduce Harmonic Distortion
Protect Your Power Quality with High-Performance LV Power Capacitors
Non-linear loads like VFDs easy to bring severe harmonic distortion in modern power networks, which causes voltage ripples, power loss, and expensive utility fines. LTECPower’s LV capacitors are engineered to address the power quality challenges directly.
Our low-voltage capacitors are built with optimized metallized polypropylene film and specialized wave-cut edges. The advanced MPP technology ensures maximum current-handling capacity in areas that withstand intense thermal and electrical stress.
Housed in compact cylindrical aluminum cases filled with biodegradable, non-toxic plant oil or semi-dry resin, our capacitors are 00% PCB-free, and require no maintenance.
Fully compliant with IEC/EN 60831-1/2 standards, the capacitors ensure you reliable, continuous operations in high-temperature ambient environments up to +55℃ / +60℃.
Ideal for automatic capacitor bank builders, the capacitors are perfectly matched in harmonic if you pair them with our detuned reactors. They can effectively eliminate network resonance and prevent unexpected nuisance trips.

Secure Your Power Factor Correction with High-Density LV Capacitors
Using high-grade metallized polypropylene film with exceptional self-healing properties, LTECPower’s LV capacitors prevent transient voltage spikes and continuous overloads from ruining your electrical components.
When a voltage spike punctures the dielectric layer, our power capacitor delivers you a microsecond automatic repair to keep it from turning into catastrophic grid failures. The self-healing only causes a microscopic capacitance drop of less than 100pF, a negligible capacitance loss. The heavy-duty film technology greatly extends the power factor correction equipment’s service life.
Each of our power capacitors integrates a failsafe mechanical overpressure disconnector to prevent dangerous structural ruptures at the end of a capacitor’s lifespan.
The destructive internal thermal stress or gas buildup may cause your cylindrical aluminum to expand outward. Once the expansion exceeds a strictly calibrated threshold, the connecting wires may be pulled apart, and then all current will be cut off.
Using eco-friendly, biodegradable resin or plant oil to flood the broken connection points, our capacitors eliminate arc flash risks and completely secure the surrounding switchgear cabinet.
By combining space-saving profiles with enhanced field installation, our low-voltage capacitors reduce your labor costs.
Our specialized wave-cut film profiling greatly minimizes the resistance and heat generation to offer you an ultra-compact footprint and saves you valuable space inside dense motor control centers and capacitor banks.
Providing you with verified IP2X shock-proof safety, our capacitors completely prevent accidental finger contact with live parts during commissioning and field maintenance.
Guaranteeing you a loose-free, high-capacity electrical connection, they can securely support large heavy-duty cables up to 25mm² and rated currents up to 80A.

Verified LV Capacitors for Demanding Industrial Applications
Seamlessly integrated into automatic capacitor banks, motor control centers, and smart grids, LTECPower’s low voltage capacitors deliver you unparalleled power factor optimization, eliminating harmonic threats and unlocking maximum power density.
Automotive and Heavy Manufacturing
The VFD loads, automated welding lines, and induction furnaces in heavy industry are easy to creating severe harmonic distortion and destructive current spikes. With optimized wave-cut metallized film, our capacitors can drastically minimize internal heat and resistance, and safeguard your 24/7 assembly lines from costly, unexpected downtime.
Water, Wastewater, and Municipal Infrastructure
Power disruption will destroy pumping stations and large-scale HVAC systems. Fully complying with strict IEC/EN standards and IEEE 519 harmonic regulations, our capacitors eliminate your expensive utility penalties. Filled with eco-friendly, 100% PCB-free resin, our units deliver you maintenance-free, explosion-proof protection.
Renewable Energy, Solar Plants, and Wind Farms
Certified for reliable execution up to 5,000 meters above sea level, our LV capacitors never suffer from power derating and oil leakage. Filled with eco-friendly, biodegradable semi-dry resin and designed with an operating thermal class of -40°C to +55°C, the capacitors deliver you secure reactive power compensation for grid-tie inverters with maximized clean energy uptime.
Once the capacitors are under severe thermal stress, overload, or end-of-life conditions, their internal gas pressure will cause the aluminum case to expand slightly. So the overpressure disconnector can help cleanly snap an internal notched lead wire, safely disconnecting the capacitor from the power source before any catastrophic or explosive structural damage can occur.
A localized micro-arc instantly vaporizes the ultra-thin metallized layer around the defect within microseconds if there is a dielectric puncture due to voltage surges. So the self-healing can eliminate the short circuit and isolate the fault with a negligible capacitance loss (less than 100 pF), keeping your capacitors running without interruption.
Yes. However, if there is severe harmonic distortion caused by heavy VFDs in the network,
you need to pair capacitors in series with detuned reactors (such as 7% or 14% detuning factors). The detuned reactors can increase system impedance to high frequencies and prevent dangerous electrical resonance loops that shorten component lifespans.
Our capacitors can withstand peak short-term temperatures from +55℃ to +60℃ (with a maximum 24-hour average of +45℃) for rigorous temperature categories. You can apply them for altitudes up to 4,000 meters. Filled with non-toxic, biodegradable, and 100% PCB-free soft resin or plant oil, they ensure you long-term sustainable indoor operations.
The key metrics to choose the right power capacitors for power factor correction are rated voltage range (230V to 1000V), rated frequency (50 Hz / 60 Hz), output reactive capacity (2.5 kvar to 30 kvar), and ambient temperature classes (-40℃ to +55℃). The premium capacitors must require verified dielectric withstand capabilities and built-in overpressure disconnectors.
