CE/UL Certified Dry Transformer Electrical Transformer Power Transformer

This CE/UL-certified dry-type electrical transformer is a 3-phase power transformer designed for industrial and commercial applications. With a rated capacity of 30–3,000 kVA and compatibility with 50Hz/60Hz frequencies, it features a dual-coil layered structure. It supports flexible input voltages (6–11 kV) and diverse output voltages (200–440 V), utilizing ANAF (Air Natural/Air Forced) cooling for efficient heat dissipation.

DSJ Electrical Co., Ltd. Product Features
  • Enhanced Safety & Compliance:

    Dry-type design eliminates fire/leak risks from insulating oil, meeting strict CE/UL standards for hazardous environments. Ideal for indoor installations (e.g., hospitals, data centers) with minimal safety barriers.

  • Global Voltage Compatibility:

    Wide input range (6 kV–11 kV) and output options (200 V–440 V) suit diverse grid standards (e.g., 10 kV EU grids, 400 V ASEAN systems). Dual-frequency support (50/60 Hz) ensures global deployment without retrofitting.

  • Optimized Cooling & Longevity:

    ANAF cooling combines silent natural convection with forced-air modes during peak loads, reducing thermal stress. Layered coil structure improves heat dissipation, extending service life by 15–20% vs. conventional designs.

  • Fast Lead Time:

    The fastest lead time is 20 days.
