27.5 kVA 600 V Transformer
Budget: $250 – $750 CAD
I need a 27.5 kVA power transformer engineered for an industrial setting and operating at 600 V. Efficiency and reliability are top priorities, but the unit must also remain compact enough to integrate into existing switchgear.
Key requirement: the transformer has to be completely air-cooled—no oil or water circuits—so the core, windings, and enclosure must be designed with ample ventilation and appropriate thermal margins to handle continuous duty at full load.
Here is the scope I would like covered:
• Electrical and mechanical design that meets North American safety standards (CSA or UL preferred).
• Full set of drawings, winding data, and a bill of materials ready for build or procurement.
• Losses and temperature-rise calculations to verify the air-cooling approach.
• Final test plan outlining routine tests (turn-ratio, insulation resistance, hi-pot, no-load and load losses).
If you have experience producing air-cooled industrial transformers around this rating, please describe similar projects and the design tools you use (e.g., ANSYS Maxwell, FEMM, AutoCAD). I will review proposals based on demonstrated technical depth and clarity of the development process.
