22kV Transformer Procurement Checklist
Engineering Intent
22kV transformer projects require clear insulation level, voltage ratio and installation data because they often sit between utility supply and plant distribution.
This article is written for engineers, EPC buyers and procurement teams who need to turn 22kV transformer procurement into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | 22kV primary voltage and tap range |
| Check 2 | Secondary voltage and capacity |
| Check 3 | Insulation level and surge protection design |
| Check 4 | Outdoor or indoor service condition |
Standards and Evidence to Request
- IEC 60076 series
- Utility connection specification
- Factory routine test documents
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
- No tap range in RFQ
- Ignoring surge arrester or cable box interface
- No site altitude or ambient temperature
RFQ Checklist
- Provide voltage ratio
- Confirm tap changer requirement
- State installation environment
- Request outline drawing and test report
