Detuned Reactors for Absolute Anti-Explosion Safety
Heavy industrial machinery always brings harmful harmonic currents into your electrical grid, causing overheating, swelling, or explosions.
To mitigate that risk, our MV capacitor banks, serving as a strong bodyguard, are built with iron-core reactors that absorb harmonic distortion and block current amplification.
Even under peak power surges, we ensure you smooth running without a loud humming noise. So your factory is protected from sudden downtime and catastrophic equipment damage.
Smart Fusing and Rapid Discharge Safety
To avoid the system tripping and shutdown by electrical faults, we build our MV capacitor banks with an intelligent internally fused design.
If a fault occurs, the fuse will isolate it in milliseconds. So your capacitor bank runs continuously without downtime.
Our built-in discharge resistors can automatically bring your high voltage down to safe levels below 50V within 5 minutes, ensuring you safey and stability.
Weatherproof IP55 Enclosures for Long Service Life

Stop your capacitor swelling, switch tripping, and the capacitor bank lowers your monthly electricity bills by 5% to 10% from day one.
Utility-Scale Wind and Solar Farms
Large wind generators and solar inverters in modern green energy sites are allowed to connect and sell electricity if they meet strict grid power quality standards.
To ensure a fast and safe grid connection, our MV capacitor banks are fully IEC 60871-1 compliant. With heavy-duty series reactors to absorb dangerous high-current shocks, our capacitor bank is built with a rugged, weatherproof IP55 enclosure.
Preventing rid resonance, we ensure your capacitor bank runs smoothly even under extreme desert heat or coastal humidity.
Water Pumping Plants and Utility Substations
Desalination pumps, water purification stations, and utility substations in large municipal sites require perfect power stability from massive outages.
Optimizing your network by clearing out wasted electricity, our automatic power factor correction system can safely balance your system voltage without overloading heavy power cables.
Eliminating strict utility penalty fines, our MV capacitor banks safely unlock hidden capacity in your existing transformers.
So, reducing your cost on new hardware, the capacitor bank ensures you zero project downtime.

Installed in high-power systems (1 kV to 38 kV), the MV capacitor bank is an integrated electrical panel to clear out wasted "reactive power" from heavy industrial machinery.
Designed to optimize your grid's efficiency, it can stabilize your factory voltage and protect your cables from overheating. In the end, your system will avoid penalty fines from the utility company caused by the low power factor.
Heavy machines like cement mills and large water pumps always bring your electrical system massive reactive waste. That waste would lead to heavy power factor fines.
By raising your power factor to perfect levels, our capacitor banks can prevent utility penalties and lower your factory electricity bills by 5% to 10%.
Their main difference is adaptability.
Fixed MV Capacitor Bank
Only providing a constant, unchanging amount of power compensation, the fixed capacitor bank is perfect for individual large motors always running at the same speed.
Automatic MV Capacitor Bank
With an intelligent microprocessor brain, the automatic capacitor bank can automatically switch the internal capacitor stages on or off according to your fluctuating industrial grids.
And we deliver both.
To avoid the capacitors overheating or exploding caused by the harmful harmonics from heavy factory machines, you need to connect heavy-duty detuned reactors inside every panel.
Acting as a bodyguard, the reactors can safely block these destructive currents to keep your system perfectly cool and 100% safe.
Engineered with built-in micro-fuses inside our capacitors, they can instantly cut off the faults once there are any failures. They can keep your factory from sudden, costly production downtime due to any minor failure.
Yes, it is 100% safe.
Our MV capacitor banks can still hold lethal trapped high voltage, even after disconnection. With built-in discharge resistors, they can drain the dangerous voltage within 5 minutes of shutdown. It is totally safe for your maintenance.
By splitting the capacitors into two balanced groups, we can ensure balanced power inside. If there are any failures, our system can detect and trip the main breaker instantly.
Yes, absolutely.
Constructed with a heavy-duty, 2mm thick IP55 stainless steel enclosure, our capacitor bank can block out driving rain, desert sandstorms, and salty coastal air.
The trapped-key interlock system is a mechanical safety lock that requires a strict, foolproof opening sequence.
It locks the panel doors securely until the main power is completely turned off and the system is grounded. The interlock system can be assured to be 100% safe.
Yes, absolutely.
Designed and fully tested in compliance with IEC 60871-1, IEEE, CE, and TÜV, our MV capacitor bank ensures you pass strict engineering audits.
