YAWEI Power Transformer 66KV 110KV 220KV MV&HV Electrical Use High QUITALITY

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Conversion: Efficiently converts high-voltage inputs (66KV, 110KV, 220KV) to lower output voltages (220V, 11KV), enabling seamless power distribution across medium and high-voltage (MV&HV) systems.
  • Three-Phase Power Handling: Designed with a Ynd11 vector group configuration to ensure balanced load distribution and stable three-phase power transmission for industrial and commercial applications.

Key features

  • 1. Corrosion-Resistant Metal Construction for Durable Performance

    • With a robust metal body (steel/aluminum) and corrosion-resistant coating, the YAWEI Power Transformer ensures long-term reliability in harsh outdoor environments. The optimized cooling fins further enhance heat dissipation, maintaining efficiency under continuous operation compared to traditional sealed designs*.

  • 2. Wide Voltage Conversion Range for Versatile Applications

    • With a flexible voltage conversion capability (66KV-220KV input to 220V/11KV output), you can seamlessly adapt to diverse power distribution needs, from industrial complexes to commercial grids. Its YNd11 vector group design improves compatibility with high-load scenarios* compared to single-vector models.

  • 3. UL-Certified Safety and Compliance

    • Equipped with UL certification, the transformer meets rigorous safety and performance standards, ensuring compliance with global commercial and industrial regulations. This certification provides peace of mind for critical power systems* compared to non-certified alternatives.

  • 4. Easy-Maintenance Design for Reduced Downtime

    • With a modular top cover and accessible internal components, routine maintenance and inspections are simplified, reducing downtime by up to 30%* compared to traditional sealed transformers. The vented design further aids in safe, efficient heat management.

  • 5. ONAN Cooling System for Efficient Heat Dissipation

    • The ONAN (Oil-Natural Air-Cooled) system ensures stable operation even under high loads, extending component lifespan and minimizing energy loss. This design outperforms passive cooling models in reliability for 24/7 commercial use* compared to basic oil-immersed alternatives.
