500kVA Transformer RFQ Checklist
Engineering Intent
A 500kVA transformer inquiry should include enough electrical and site data for a comparable quotation.
This article is written for engineers, EPC buyers and procurement teams who need to turn 500kVA transformer RFQ into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | Voltage ratio and frequency |
| Check 2 | Dry type or oil immersed design |
| Check 3 | Vector group and impedance |
| Check 4 | Indoor or outdoor installation |
Standards and Evidence to Request
- IEC 60076 series
- Project drawing approval package
- Routine test report
For project approval, request a technical datasheet, outline drawing, wiring or terminal diagram where applicable, routine test report and nameplate information before shipment.
Common Specification Mistakes
- Comparing copper and aluminum designs as if equal
- No enclosure IP rating
- No destination country or frequency
RFQ Checklist
- State 500kVA capacity
- Confirm voltage ratio
- Select winding material preference
- Request datasheet and outline drawing
