Dry Type Transformer IP Enclosure Selection
Engineering Intent
The enclosure rating controls touch protection, dust exposure and cooling airflow for indoor dry type transformer installations.
This article is written for engineers, EPC buyers and procurement teams who need to turn dry type transformer enclosure rating into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | Indoor locked room or public area |
| Check 2 | Dust, humidity and access level |
| Check 3 | IP00, IP20, IP23 or IP31 requirement |
| Check 4 | Cable entry direction and ventilation clearance |
Standards and Evidence to Request
- IEC 60076-11
- IEC 60529 ingress protection reference
- Project safety and access requirement
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
- Requesting high IP rating without checking heat dissipation
- Forgetting cable entry direction
- Installing IP00 units where public access is possible
RFQ Checklist
- State enclosure IP rating
- Confirm cable entry top or bottom
- Provide room access condition
- Confirm color and enclosure material if specified
