Transformers for Data Centers
Data center loads do not behave like factory loads. They step, they hold a flat high plateau, and they run nonstop. We build dry type and oil immersed transformers for colocation halls, edge sites and AI compute buildings, sized on the real load profile rather than a nameplate guess.
What the load looks like
- Continuous high load with very little daily variation.
- Non-linear loads from UPS systems, server power supplies and drives.
- Harmonic content that pushes extra loss into the windings.
- Tight footprint and weight limits inside the electrical room.
- Strict fire and indoor safety rules for anything installed inside the building.
What we recommend
Dry Type Transformer
Indoor electrical rooms, fire-safe cast resin, 50 to 6000 kVA.
Oil Immersed Transformer
Outdoor yard or separate substation building.
Medium Voltage Transformer
11 kV, 22 kV and 33 kV primary for campus distribution.

| Standards | IEC 60076, IEC 60076-11 |
Practical notes
- Harmonic mitigation (K-factor) is a design option, not a standard order item.
- Two units in parallel are often cheaper than one oversized unit, and give N+1.
- Give us the real load profile and power factor so the temperature rise is realistic.
- Confirm the room height and the door width before the order, not after delivery.
Questions buyers ask
Dry type indoors where fire safety rules apply. Oil immersed when there is an outdoor yard or a separate substation building.
Yes. Tell us the harmonic spectrum or the K-factor you need and we will design the winding and the cooling to match.
Typically 30 days after drawing approval, depending on rating and quantity.
Usually. Send the outline drawing or a nameplate photo and we will check the footprint and terminal positions before quoting.
Send us the specification
Rating, primary and secondary voltage, frequency, quantity and the application. We answer within one working day.
