Transformer and Switchgear Package RFQ Checklist

Engineering Intent

A package RFQ should coordinate transformer, MV switchgear, LV switchgear, CT/VT, cables and protection documents in one technical schedule.

This article is written for engineers, EPC buyers and procurement teams who need to turn transformer and switchgear package RFQ into a clear technical request instead of a vague product inquiry.

Key Selection Data

Item	Data to Confirm
Check 1	Single-line diagram
Check 2	Transformer schedule
Check 3	MV and LV feeder schedule
Check 4	Protection and metering requirements

Standards and Evidence to Request

• IEC 60076
• IEC 62271
• IEC 61439
• Project FAT and documentation requirements

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

• Buying transformer and switchgear from separate schedules with mismatched ratings
• No CT/VT data
• No cable entry planning

RFQ Checklist

1. Attach SLD
2. Provide transformer and feeder schedule
3. State standards
4. Request coordinated drawing package
