Transformers for Infrastructure
Infrastructure projects are judged on the schedule and the paperwork. The transformer has to arrive on a date, match the specification in the tender, and come with the test report that the client’s engineer will ask for. We build units for utility distribution, water and wastewater plants, rail, ports and public buildings, with the documentation pack your project needs.
What the load looks like
- Long project cycles with a fixed energisation date.
- Tender specifications that name the standard and the test regime.
- Mixed loads: pumps, HVAC, lighting, signalling and traction.
- Sites that are far from the factory and hard to reach for a repair.
- Client engineers who will ask for the routine test report on delivery.
What we recommend
Distribution Transformer
Utility and public works distribution, 50 to 3150 kVA.
Oil Immersed Transformer
Outdoor substations for water, rail and port projects.
Medium Voltage Transformer
11 kV to 33 kV distribution and step-down.

Practical notes
- Send the tender document. We quote against the specification, not a generic datasheet.
- Export packing is standard for shipment; tell us the port and the handling method.
- Routine tests are issued with every unit. Type test reports are available on request.
- Give us the energisation date early so the production slot can be reserved.
