Transformers for Manufacturing
Manufacturing sites add capacity in steps. We supply the first unit and, later, a second unit that runs in parallel with the first, matched on ratio and impedance.
What the load looks like
- Load that grows with each new line.
- Several transformers in parallel on one bus.
- Sensitive control equipment that needs a stable voltage.
What we recommend
Distribution Transformers
Standard step-down duty.
Three Phase Transformers
Dyn11 or Yyn0.
Dry Type Transformers
Indoor installation.
Specification notes
| Typical rating | 500 – 3150 kVA |
|---|---|
| Primary voltage | 11 / 22 / 33 kV |
| Secondary voltage | 400 / 415 V |
| Frequency | 50 Hz or 60 Hz |
| Parallel operation | Matched ratio, vector group and impedance |
| Standard | IEC 60076 |
Practical notes
- For parallel operation, order both units together or send us the existing nameplate.
- Keep the tap position identical on units that share a bus.
Questions buyers ask
Typically 30 days after drawing approval, depending on the quantity.
Yes. Test report, outline drawing and a terminal diagram go out with the unit.
Usually. Send the old nameplate or the outline drawing and we will check the footprint, terminal positions and loss figures before quoting.
Rating, primary and secondary voltage, frequency, vector group, quantity, application and the ambient conditions. A drawing or a nameplate photo settles the rest.
Send us the specification
Rating, primary and secondary voltage, frequency, quantity and the application. We answer within one working day.
