MV Power Capacitors Deliver 20 Years of Reliable Energy Savings
Our capacitors eliminate traditional performance degradation and withstand sustained overvoltages without overheating, with a premium polypropylene film-foil dielectric system.
Keeping your internal power losses below 0.2W/kVAR, our capacitors can be operated at an exceptionally low temperature, completely preventing early thermal aging of internal cells.
Designed with superior thermal margin, the MV capacitors guarantee you an outstanding 95%+ field survival rate over a 20-year operational lifecycle in standard industrial environments.
Each module of our capacitors is equipped with a heavy-duty, 50,000A current-limiting safety fuse to protect your system against dangerous line-to-ground faults.
Built-in mechanical pop-up indicator, every fuse automatically extends outward the moment a fault occurs.
With simplified routine maintenance, you can instantly spot a blown fuse with a single glance. The capacitors eliminate the need for technical troubleshooting tools and fully safeguard your downstream assets.
Built with heavy-duty steel all-weather enclosures, our MV capacitor assemblies offer you complete indoor dustproof and outdoor weatherproof protection. It is perfect for remote oilfields, mining sites, and utility substations.
All the cells are submerged in non-PCB, biodegradable insulation fluid for eco-safe fluid insulation. The capacitors deliver you elite dielectric strength while meeting strict international environmental standards.
Even under extreme climates, our capacitors are safe to handle cold-weather startups down to -40°C and withstand blistering summer heat up to +46°C without performance loss.

Where Our MV Capacitors Are Used: Smart Solutions for 3kV–12kV Industrial Grids
Seamlessly integrated into indoor switchgear panels and large induction motors, our MV capacitors protect your heavy-duty operations from costly power factor penalties, voltage drops, and energy waste.
Space-Saving MV Capacitors Built for Easy Switchgear Integration
Designed to perfectly match the switchgear, enclosures, VCBs, and protection relays, our capacitors offer a broad capacity range from 50kVar to 500kVar to fit your network requirements. With a highly compact, IP00 open design, our units minimize your footprint and save your valuable space. Our quick, seamless copper busbar connections significantly cut down your labor time.
Protecting Heavy Industrial Motors from Overheating and Voltage Drops
Perfect for heavy-duty equipment like induction motors, slip-ring motors, soft starters, and motor control centers, our MV capacitors provide you with instantaneous power factor correction right where it’s needed most. Operated reliably up to 50°C via efficient natural air cooling, our units reduce starter thermal stress and significantly extend the lifespan of your heavy-duty motorized equipment.
Eliminate Grid Penalties and Free Up Transformer Capacity
Widely applied in substation infrastructure with power transformers, distribution busways, overhead lines, and incoming bays, our capacitors optimize your efficiency at the main power entry point. Instantly stopping utility penalties, the capacitors reduce internal distribution line losses and free up blocked transformer capacity for expanded production.
By correcting reactive power directly, our MV capacitors reduce voltage drops, free up your transformer capacity, improve your power factor, and lower overall energy losses across your plant distribution lines. So your utility penalties can be largely cut down.
Every our capacitors are integrated a safety fuse with a massive 50,000-ampere interrupting capacity. They can isolate the compromised cell in milliseconds under an internal fault or insulation breakdown. So the MV capacitors eliminate catastrophic cell rupture and cascading system damage.
Even after you turn off the power, the MV capacitors can store dangerous electrical energy. The internal discharge resistors inside capacitors can automatically drain this leftover voltage down to safe levels within 5 minutes. So it is safe for your workers.
No. The MV capacitors are built only for clean, non-harmonic networks. The capacitors will overheat and fail early if you install them in an environment with high harmonics. So for harmonic networks, you need to pair specialized tuning reactors.
Our MV capacitors are reliably operated from -25℃ to +50℃, and ensure you have stable natural air cooling in both cold winters and hot indoor factory environments.
