Compare the 138/13.8 kV equipment records
The comparison uses the same public records as J&J's inventory. A candidate's stated quantity, condition and evidence basis stay attached to that record. A public opportunity is a starting point for the technical package and current written offer.
- 50 MVA-Class 138/13.8 kV Substation Package - details and document request
- 65 MVA 138/13.8 kV Reconditioned GSU - details and document request
| Equipment record | Published MVA | Listed quantity | Condition and evidence basis |
|---|---|---|---|
| Manufacturer to confirm · JJ-TX-007 | 30/39.9/50 MVA at 55 C; 33.6/44.7/56 MVA at 65 C | 1 represented design package | Brand new, never used and never energized; 2024 approval drawings reviewed; serial identity requires confirmation. Project-specific supplied approval drawings reviewed; final equipment OEM and serial identity require confirmation |
| ABB · JJ-TX-209 | 39/52/65 MVA at 65°C rise | One unit; current allocation subject to written confirmation | Reconditioned used transformer; refurbishment completed in 2022. ABB identified by the supplied replacement nameplate and historical refurbishment/test report; original OEM provenance to confirm |
What matters when buying a 138/13.8 kV transformer?
A 138/34.5 kV main winding does not supply a 13.8 kV load bus merely because the unit has a 13.8 kV tertiary. Specify the intended load winding, neutral and grounding, MVA at the required cooling stage, tap-changing duty and the project one-line. A drawing package with serial identity outstanding remains a different evidence basis from an identified in-service or reconditioned unit.
- Compare required continuous MVA with the actual cooling-stage and temperature-rise ratings.
- Identify new-project, spare, replacement or proposed parallel-operation duty.
- Request the nameplate, connection and outline drawings, available tests, condition history and included accessories.
New, unused or reconditioned: compare the actual offer
State the condition your project accepts, then review the selected record's identity, service or preservation history, inspection scope and written availability. Submitted inventory and design records require their own confirmation; an unused description does not establish a current warranty or a ready-to-ship package.

Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Does J&J sell 138/13.8 kV transformers?
J&J Transformers LLC accepts 138/13.8 kV transformer requirements for data centers, utilities, industrial plants and EPCs. Compare the 138/13.8 kV design package and reconditioned GSU record below by continuous MVA, winding connections, condition and documentation. Contact Tommy for the selected unit's technical package, price and current written availability.
How do I get a 138/13.8 kV transformer price?
Call Tommy Marco at 346-276-9540 or email tommy@jjtransformers.com with the required ratings, quantity, destination and needed-on-site date. Include the exact unit reference if you have selected a listing. Pricing and delivery apply to the confirmed configuration and included scope.
Can I request a 138/13.8 kV transformer that is not listed?
Yes. Send the requirement to Tommy with continuous MVA, winding connections, operating duty, quantity and required date. J&J can review other sourcing options; an inquiry is not a statement that every configuration is in stock.
Are matching 138/13.8 kV units automatically interchangeable?
No. Compare the exact connection, grounding, impedance and base, taps, insulation, frequency, cooling, condition and physical interfaces. A same-ratio candidate needs project-specific engineering acceptance, especially for parallel operation or a different operating direction.
