Dry-Type Phase-Shifting Transformers for Industrial Power Quality
Eliminate Industrial Harmonics with Phase-Shifting Rectifier Transformers
Your factory needs heavy industrial machinery, but it always creates silent power pollution with harmful harmonics to drain your grid. To help you prevent equipment overheating, cut your costs and downtime, we engineered the dry-type phase-shifting transformers to shield your plant.
With precise, built-in angle-shifting, the transformers run quietly to cancel out disruptive harmonics at the source, absorbing the electrical stress to protect your sensitive downstream machinery.
More than just efficient, compliance-certified, our rectifier transformer is an asting investment to keep your power clean and stable. Securing your equipment’s lifespan, they help eliminate your unexpected breakdown worries and safeguard the daily continuity of your business.

The Ultimate Power Protection: Heavy-Duty Performance Built to Last
Just like high-end headphones cancel out noise to give you quiet, our phase-shifting transformers can help eliminate harmful electrical noise before it harms your plant.
Perfectly misaligning 3 to 10 internal winding groups, our rectifier transformer creates a clever, built-in cancellation network. Forcing disruptive harmonics to collide and destroy each other naturally, our transformer keeps your primary power network perfectly clean and compliant.
By trapping the stress inside, they stop unexpected switchgear tripping and protect your nearby sensitive electronics from overheating. More than technical precision, our power transformer is a heavy-duty guardian to secure your power.
Industrial floors can be brutal. There is scorching heat, heavy loads, and severe moisture. To keep your plant powered no matter what, we build the phase-shifting rectifier transformers.
Wrapped in premium, H-Class or C-Class insulation with powerful air-cooling, our transformer handles the heavy machinery, and to protect the core with a solid resin shell.
Locking out up to 95% humidity, the phase-shifting transformer eliminates internal sparks or leakage risks.
Carrying globally recognized certifications like UL, CE, TÜV, and EAC, our transformers are built to travel the world, meeting the strictest international benchmarks, giving your team total peace of mind.
Using heavy-duty copper busbars to maximize electrical contact and eliminate energy waste, our transformer is highly adaptable. Our wide ±10% voltage tolerance and adjustable tap gears can keep your power smooth and steady.

Engineered for the Extremes: Powering Heavy Industry's Hardest Operations
From dusty deep mines and high-humidity water plants, our transformer can endure. Eliminating severe harmonics at the source, they safeguard your most expensive electronics, no matter how harsh the environment.
Mining and Heavy Material Handling
Heavy mining equipment keeps your plant running, but also causes severe dust and unstable power risk unexpected, costly downtime. Acting as the ultimate shield, our phase-shifting transformer cancels harmonics at the source and eliminates underground fire risks. Built with a rugged, oil-free design, it thrives in the harshest environments for long, stable runs.
Water and Wastewater Management
Municipal water facilities require absolute reliability. To stop the electrical noise from massive pumps and prevent heavy grid penalties, our recrifier transformers can fix it. With 95%+ efficiency and 95% humidity resilience, our transformers eliminate harmful interference right at the pump station. Keeping your electronics fully compliant ensures a safe, worry-free flow of clean water to your community.
Built for the Extreme: Chemical and Metallurgical Power
Electrochemical plants demand massive, uninterrupted power. However, the intense heat and electrical stress will burn out your standard transformers. Built to endure this stress, our phase-shifting transformers smoothly stabilize your currents while shielding expensive rectifiers from damage. Taking on the thermal strain, our transformers ensure your line is safe, efficient, and running long into the future.
VFDs are great for control, but they bring harmful electrical noise, damaging your equipment, and cause power penalties. Acting as a built-in shield, our phase-shifting transformer protects your sensitive electronics by canceling out these disruptive harmonics right at the source, to ensure you have smooth, worry-free operations without spending extra on costly external filters.
Secondary winding groups are your transformer’s defense line. The more groups you have (from 3 to 10), the more precision you can shift the electrical angles. Those alignment forces harmful harmonic waves to collide and cancel each other out. Adding more groups, our transformers ensure you a much cleaner power supply and maximum safety for your sensitive equipment.
Absolutely. Built to adapt unpredictable grids, our phase-shifting transformers naturally absorb voltage fluctuations up to ±10%. With a flexible manual adjustment for an extra ±5% fine-tuning, they ensure you a dual layer of protection for a rock-solid, stable voltage.
Manufactured and tested to strictly global standards, IEC 60076-11 for dry-type safety, IEC 61378-1 for dedicated rectifier performance, and UL 1446 for heat resistance, our rectifier transformers can pass any local inspection and run safely anywhere in the world.
