Single-unit requirements and multi-unit collector projects
Specify whether you need one replacement, several matching units, or a staged release. A group listing and a single documented unit require different quantity and document checks. Request the records for each proposed unit before treating a group as interchangeable.
- State the required MVA at each cooling stage, not only the highest nameplate rating.
- Identify whether a tertiary is required, what it serves, and the acceptable voltage and rating.
- For multiple units, identify matching requirements and any intended parallel operation for engineering review.
- Separate the total project quantity from the quantity needed for the first delivery.
Send a requirement that can be matched
Start with MVA, quantity, project state, and needed-on-site date. Add the one-line or specification through direct follow-up with Tommy. The RFQ below already includes this voltage ratio.
| Requirement | What to provide |
|---|---|
| Equipment duty | Collector step-up, GSU, substation, replacement, or other defined duty |
| Electrical fit | MVA by cooling stage, winding arrangement, tertiary duty, impedance basis, taps, and frequency |
| Project constraints | Quantity, state, receiving date, footprint, origin restrictions, and controlling specification |
| Commercial scope | Required documents, inspection, included accessories, freight, loading, and acceptance conditions |
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Can I source several 138/34.5 kV transformers together?
Send the total quantity, the required ratings, and a release schedule. J&J can review the public group and single-unit opportunities against that requirement. Group identity, individual records, quantity remaining, and availability must be reconfirmed before a proposal.
What if no listed 138/34.5 kV transformer meets my MVA requirement?
Send the full requirement anyway. J&J can review sourcing options without representing an unconfirmed unit as available. Include acceptable alternatives only when your engineering team has approved them.
Can I receive drawings and pricing?
Contact Tommy Marco at 346-276-9540 or submit an RFQ with the unit reference and project details. J&J will review document access, current availability, scope, and price for that candidate. Public equipment pages do not constitute a quotation.
