Advantages for a Superior User Experience

  • Low Loss: No-load loss is reduced by 20% compared to national standards, and load loss is reduced by 5%.

  • Low Noise: Natural cooling noise levels are below 60dB, 3 to 5dB lower than national standards.

  • Low Partial Discharge: Dust-free operations keep partial discharge levels below 100pC.

  • Short Circuit Resistance: Passed sudden short circuit tests at the National Transformer Testing Center.

  • Leakage-Free: All sealing components are made from acrylic in one piece and undergo fluorescence, positive pressure, and negative pressure leak tests.

Our Core Seven-Level Temperature Control Technology

We ensure optimal performance and reliability under various conditions through advanced temperature control of insulation materials, liquid flow circuits, overload protection, iron cores, seals, components, and short circuits.



Craftsmanship and Quality Pursuit

  • Utilizes a fully enclosed manufacturing process with constant temperature and humidity control in a dust-free environment, ensuring meticulous quality control.

  • The core material is high magnetic permeability silicon steel, produced using a fully automated Swiss-imported cross-cutting and stacking robot production line.

  • The coil's guided oil circulation structure ensures a product design lifespan of 30 years.

  • The tank adopts a minute bell-type and barrel-type structure with precise sealing limits and undergoes three leak tests.
