D13 Series Single-Phase Oil-Immersed Distribution Transformer
Product Overview

The D13 Series Single-Phase Distribution Transformer is a next-generation, eco-friendly, and energy-efficient solution developed by JNCN Power. Specifically designed to align with American ANSI standards while optimizing for global 10kV power systems, this series is the premier choice for decentralized power distribution.

It is widely deployed in urban street lighting, high-end residential areas, railway signaling, and rural electrification projects. Its compact design and superior efficiency make it ideal for both new installations and energy-saving grid retrofits in remote or mountainous regions.

Ordering Information (Selection Guide)

To provide the most accurate solution, please specify:

  1. Rated Capacity (kVA)
  2. Voltage Ratio (e.g., 10kV / 0.23kV × 2)
  3. Performance Level Required (D11, D13, or D20 type)
  4. Installation Environment (Altitude, Temperature, and Humidity)
  5. Special Protection Requirements (e.g., enhanced corrosion resistance for coastal areas)
Why Choose JNCN D13 Single-Phase Transformers?
  • Innovative Wound Core Technology Our cores are manufactured using a specialized continuous wound core process. This seamless design eliminates traditional air gaps, significantly reducing magnetic resistance and core losses. After professional annealing treatment, the mechanical performance is enhanced, resulting in ultra-low noise levels and minimal temperature rise.
  • R-Type Dual-Column Structure The core features a sophisticated R-type single-frame dual-column wound structure. By using point welding on the outermost layer instead of traditional binding, we preserve the integrity of the magnetic flux. We utilize premium cold-rolled silicon steel (including 30Q130, 272H120, and 232H90) to ensure peak performance across different model variants.
  • High-Efficiency Low-Voltage Output With a low-voltage configuration of 2 × 0.23kV, the transformer’s LV current is only half that of conventional single-phase units. This revolutionary design reduces line losses to 1/4 of standard transformers, dramatically improving the overall economy of the distribution system.
  • Maintenance-Free Hermetic Seal The fully sealed tank prevents contact between the transformer oil and the atmosphere. This eliminates moisture absorption and oxidation, maintaining the insulation’s dielectric strength and preventing material aging. The result is a significantly extended service life with zero routine maintenance.
