High-voltage transformer intake

Sell 230 kV, 138 kV, 345 kV, and 34.5 kV Transformers

J&J Transformers LLC, based in Sugar Land, Texas, is a U.S. buyer and remarketer of document-backed transmission, substation, collector-system, and generation transformers. J&J buys, sells, and sources 230 kV, 138 kV, 345 kV, and 34.5 kV equipment nationwide. A voltage class alone is not enough to evaluate a unit. Owners should submit the complete ratio, MVA ratings, frequency, impedance, vector group, BIL, tap arrangement, serial number, location, condition, photographs, documents, environmental status when relevant, authority, loading scope, and commercial expectations. J&J reviews those facts before pursuing purchase or remarketing. No voltage class guarantees interest, an offer, or a completed transaction.

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.

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 buyer 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?

Use the seller intake, call Tommy Marco at 346-276-9540, or email tommy@jjtransformers.com. Submission is not acceptance or an offer.

What do equipment owners ask before submitting?

These answers explain the ownership, evidence, condition, environmental, logistics, and commercial questions equipment owners ask most often. 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.
