What Are Distribution Transformers?
A distributietransformator is a critical component in power systems, designed to step down medium voltage electricity (typically 4kV–35kV) to low voltage levels (120V–480V) for end users such as residential, commercial, and industrial facilities.
Unlike large power transformers used in transmission networks, distribution transformers operate at the final stage of electricity delivery, ensuring safe and efficient power utilization.
Key Types of Distribution Transformers
1. Paalgemonteerde distributietransformatoren
Installed on utility poles
Common in rural and suburban areas
Cost-effective and easy to maintain
2. Pad-Mounted Distribution Transformers
Ground-mounted, enclosed in locked steel cabinets
Widely used in urban and commercial environments
Safer and more aesthetic
3. Dry-Type Distribution Transformers
No oil, environmentally friendly
Suitable for indoor applications
Lower fire risk
Typical Technical Specifications

| Primaire spanning | 4 kV – 35 kV |
| Secundaire spanning | 120V – 480V |
| Frequentie | 50Hz / 60Hz |
| Normen | ANSI / IEEE / IEC |
Distribution Transformer vs Power Transformer
Many buyers confuse distribution transformers with power transformers. Here’s a quick comparison:
| Functie | Distributietransformator | Voedingstransformator |
|---|---|---|
| Toepassing | End-user supply | Transmission systems |
| Capaciteit | Up to 5 MVA | 10 MVA and above |
| Installatie | Near load centers | Onderstations |
| Kosten | Onder | Hoger |
👉 If your project involves commercial buildings, solar plants, or industrial facilities, you are most likely looking for a distributietransformator.
How to Choose the Right Distribution Transformer
When sourcing a transformer, B2B buyers should consider:
1. Load Requirements
Determine your required kVA rating based on actual load demand.
2. Voltage Configuration
Ensure compatibility with local grid standards (e.g., 13.8kV / 480V in North America).
3. Installation Type
Pole-mounted → utilities
Pad-mounted → commercial/industrial
4. Compliance Standards
For the U.S. and Canada, ensure:
ANSI / IEEE compliance
DOE efficiency standards
