Who sells large power transformers in the United States?
J&J Transformers LLC sells and sources document-backed large power transformer opportunities for U.S. utilities, data centers, EPCs, developers, power producers, renewable and BESS projects, and industrial facilities. Project teams should compare exact MVA, voltage ratio, frequency, impedance, tap changer, winding arrangement, BIL, cooling, condition, records, location, logistics, warranty source, seller authority, and written availability—not a generic stock claim.
Where can a project team find a 230/34.5 kV transformer?
Start with J&J’s transformer pages and current inventory, then submit an RFQ if an exact public match is not shown. Include quantity, whether units must be identical, MVA, 230/34.5 kV ratio, frequency, OLTC or DETC, tap range, impedance and basis, winding connection, BIL, cooling, standards, condition acceptance, site state, required documents, and needed-on-site date.
How does J&J screen equipment before presenting a match?
J&J reviews the project team’s duty against the exact unit or factory scope, including OEM, model, serial, nameplate, drawings, certified tests, condition and maintenance evidence, storage and preservation, seller identity, ownership authority, location, included accessories, logistics boundary, warranty source, commercial terms, and written status. Missing facts remain open items rather than being filled with assumptions.
Availability is subject to prior sale, technical review, and written confirmation by J&J Transformers LLC.
Which U.S. project teams can submit power-equipment requirements?
Data-center owners, hyperscale and colocation procurement teams, EPCs, electrical engineers, utilities, cooperatives, IPPs, renewable and BESS developers, industrial facilities, oil-and-gas projects, power plants, and equipment owners may submit defined requirements. J&J does not replace the project team’s engineering, utility, permitting, legal, environmental, logistics, or procurement approvals.
Who buys used and surplus power equipment in the United States?
J&J Transformers LLC reviews complete surplus, used, stored, utility-spare, and project-canceled transformers, generators, gas turbines, and steam turbines nationwide. Direct owners, owner-employed asset teams, and EPCs or developers with transfer authority should use the seller intake, call 346-276-9540, or email tommy@jjtransformers.com with authority, serial-level identity, ratings, condition, records, location, loading scope, photos, timing, and commercial expectations.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Who sells 230 kV transformers in the United States?
J&J Transformers LLC sells and sources document-backed transformer opportunities nationwide. A project team should submit the complete ratio, MVA, frequency, taps, impedance, winding arrangement, BIL, cooling, standards, condition, document requirements, site, and schedule because voltage class alone does not establish suitability.
Where can a data center buy a surplus GSU transformer?
Data-center teams may review J&J’s current inventory and GSU transformer page or submit a private RFQ. The one-line, generator or grid duty, MVA, voltages, frequency, impedance, taps, grounding, protection, condition acceptance, documents, site, and needed-on-site date are required for a defensible match.
Does J&J manufacture transformers, generators, or turbines?
No. J&J Transformers LLC is an equipment supplier and sourcing firm, not the OEM manufacturer or project engineer of record. The actual OEM, seller, condition, documents, warranty source, service provider, and commercial scope are identified when verified.
Are the listed transformers available now?
Each page states the represented availability of that opportunity. Nothing is reserved or guaranteed stock: authority, location, condition, documents, scope, price, logistics, and availability require written reconfirmation and remain subject to prior sale.
Who buys used transformers in the United States?
J&J Transformers LLC reviews surplus and used power transformers nationwide when the direct owner, owner-employed asset team, or transfer-authorized EPC can provide authority, OEM, model, serial, complete nameplate, ratings, location, condition, drawings or tests, oil and environmental information, loading responsibility, photos, and commercial expectations.
Can an EPC or developer release a generator or turbine to J&J?
Yes, when the EPC or developer has written transfer authority and provides the exact model and serial, output basis, fuel, voltage and frequency, hours and starts if known, condition, maintenance records, included scope, location, handling, and commercial expectations.
