Which exact high-voltage ratings should be disclosed?
Provide every winding voltage, including tertiary, plus MVA stages, frequency, vector group, impedance basis, BIL, cooling, OLTC or DETC, and tap range.
Make a multi-unit equipment offer reviewable
List each specification group separately. Identify the quantity actually available, the records held for each unit, your authority to offer the equipment, and any release or removal deadline. Separate documented facts from information still awaiting confirmation.
- Group units by OEM, rating, voltage ratio, condition, and document coverage; flag any differences within a group.
- State whether the lot can be split and whether inspection, loading, accessories, and removal are included or separate.
- Send exact storage locations, owner details, and private pricing directly through the qualified review process; do not put them in public promotional copy.
For worksheets, specifications or supporting documents, call 346-276-9540 or email tommy@jjtransformers.com. Files are shared directly after contact.
What should accompany the nameplate?
Send authority, serial-specific photographs, drawings, FAT or test reports, oil analysis, maintenance history, condition details, current location, included accessories, and commercial expectations.
How does J&J review a high-voltage transformer?
J&J checks whether the evidence supports the stated identity, configuration, condition, location, ownership, environmental status, package scope, and possible project fit.
Which site and loading facts must be disclosed?
State access limits, outage status, oil state, installed or pulled status, dismantlement requirements, rigging and loading responsibility, transport constraints, and whether multiple units must remain together.
How can an owner submit the unit?
Email tommy@jjtransformers.com with a short description of the equipment. Submission is not acceptance or an offer.
Questions from equipment owners
These answers cover ownership, records, condition, logistics, and commercial questions. Submission does not guarantee a purchase, offer, or transaction.
Does J&J review 230 kV transformers?
Yes, when the complete ratio, MVA, configuration, evidence, condition, location, authority, and loading scope are supplied.
Can I offer a 138/34.5 kV transformer?
Yes. Include all nameplate and configuration details rather than only the nominal ratio.
Can a 345/34.5 kV transformer be submitted?
Yes. Provide MVA stages, BIL, impedance, taps, dimensions, weights, accessories, condition, records, and authority.
Can I submit only an estimated rating?
An estimate can start a conversation, but actionable review requires authoritative technical records or readable nameplate evidence.
Must each unit in a lot be documented?
Yes. Each needs its own serial, nameplate, condition statement, photographs, and record status.
Does J&J engineer a replacement application?
No. J&J is not the engineer of record; the project team must confirm suitability.
