Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Three-Phase Power Distribution: Designed to efficiently transform and distribute 10kV input voltage to 0.4kV or 10kV output voltages, supporting Dyn11/Yyn0 vector groups for reduced harmonics and optimized load balancing.
  • Layer Coil Construction: Utilizes robust layer coils for enhanced thermal stability and durability under high current conditions.
  • Oil-Immersion Cooling (ONAN): Natural oil circulation combined with external fins ensures efficient heat dissipation, maintaining optimal performance in continuous operation.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a corrosion-resistant metal body and chemical-treated exterior paint, ensure durability in harsh outdoor environments. The green anti-corrosion coating provides ~30% longer lifespan than standard models*.

  • 2. Modular Interactive Design

    • With a modular design and accessible terminals/insulators, facilitate quick maintenance and component replacement compared to integrated systems*. The vertical fins and stable base enable easy installation in industrial settings.

  • 3. High-Efficiency Dyn11 Vector Group

    • With the Dyn11 vector group configuration, achieve ~15% lower energy losses and 5% higher efficiency than Yyn0 models*. This improves power distribution reliability for commercial and industrial applications.

  • 4. Versatile Three-Phase Performance

    • With three-phase operation (10kV input/0.4kV output), support continuous high-voltage distribution for long-distance power transmission. Ideal for commercial use, offering ~20% faster load handling than single-phase systems*.

  • 5. Compliance with Energy Efficiency Standards

    • Complies with S11 energy efficiency standards (e.g., IEC 60076), ensuring reduced operational costs and environmental impact. Certification details subject to manufacturer’s specifications*.
