Frequently asked questions

Tap a question to read about availability, condition, locations and equipment ratings.

Do you have Royal SMIT 525 kV transformers?

Yes. Three Royal SMIT 525/69 kV units were confirmed by J&J on October 1, 2026, with a 4–8 week shipment estimate. Request current allocation and dispatch terms. Nameplate ratings are 240/320/400 MVA, with a 250 MVA maximum for step-down duty. Photos, drawings and the supplied factory test report are available through J&J.

Are all currently listed units available?

Each record shows its dated availability basis. Earlier transformer checks and newly received offers do not guarantee present allocation. The Georgia Transformer 300 MVA 138/34.5 kV and 180 MVA 345/34.5 kV units are available for sale, confirmed by J&J on October 8, 2026. Subject to prior sale and written allocation and delivery confirmation. Request current availability, condition, allocation and delivery in writing from Tommy Marco at 346-276-9540 or tommy@jjtransformers.com.

What is the condition of J&J's current inventory?

Transformer listings distinguish new/unused equipment, used/pre-owned/rebuilt lots, stored surplus, future production and condition-unconfirmed submissions. Rebuilt and reconditioned ABB and Westinghouse lots and documented pre-owned GSUs have separate records; review each work scope, service history and test package. Generator and turbine listings include used, unused, overhauled and future-completion packages as individually stated. Every offer requires current written availability, allocation and delivery confirmation; subject to prior sale.

Is the ABB / Hitachi 220 MVA 230/34.5 kV transformer new and unused?

Yes. The ABB / Hitachi 220 MVA, 230/34.5 kV transformer, listing JJ-230-220-1, is available, brand new, never used and never energized. It was built for a project that did not proceed. Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com for specifications, pricing and current written availability confirmation. Subject to prior sale.

Where is the listed equipment located?

U.S. and international equipment locations are confirmed with each quotation. Inspection access, loading and shipping are arranged through J&J. Sugar Land, Texas is J&J’s company base, not a claim that equipment is stored locally.

Which ABB lot is rebuilt, and what are its ratings?

JJ-ABB-230-13-3 contains three rebuilt ABB 230/13.8 kV transformers, rated 40/53.3 MVA at 55 C and 44.8/59.7 MVA at 65 C. It is not a 100 MVA lot and is separate from the new, never-energized ABB / Hitachi 220 MVA 230/34.5 kV unit. Equipment location: USA. Rebuild scope and included accessories require written reconfirmation; subject to prior sale.

Do you have a 66/34.5 kV transformer?

Yes. J&J lists a WEG 54/79/90 MVA, 66/34.5 kV transformer with Dyn1 connections and low-side LTC. Its rated high side is 66 kV. Contact Tommy for the technical package and availability.

Do you have 69 kV transformers?

J&J now lists submitted 69/12.47 kV and 69/34.5 kV transformer opportunities, with condition and current allocation requiring confirmation. One public ABB 230 kV autotransformer record is reconnectable for 115 kV or 69 kV service. Send the required MVA, exact ratio, quantity, site, and needed-on-site date.

Do you have 115 kV transformers?

The public inventory includes a pre-owned ABB 115/13.2 kV GSU and a separate Westinghouse 115/24.9 kV lot representing two reconditioned 12/16/20/22.4 MVA units. All 115 kV Virginia Transformer listings have been removed following the sold update. Ask J&J for current written availability and matching technical records.

Do you have 138 kV transformers?

Yes. Public records include Georgia Transformer and Kolektor ETRA 138/34.5 kV opportunities plus a manufacturer-unconfirmed 138/13.8 kV design package. Evidence and open items differ by listing.

Do you have 161 kV transformers?

Yes. The Siemens Energy 63/84/105 MVA 161/34.5 kV transformer is brand new, never used and never energized, with a 13.8 kV additional winding. Current availability requires written confirmation; subject to prior sale.

Do you have 230/34.5 kV or 345/34.5 kV transformers?

230/34.5 kV listings include ABB / Hitachi 220 MVA, Fortune Electric 167 MVA, ILJIN 167 MVA, and WEG 88 MVA units. A distinct WEG 120 MVA offer has condition to confirm. The Prolec GE 132/176/220 MVA and Georgia Transformer 108/144/180 MVA 345/34.5 kV units are listed for quotation. Georgia availability was confirmed by J&J on October 8, 2026. Confirm the stated new/unused conditions against each unit's records. Call 346-276-9540 for specs, price and current written availability; subject to prior sale.

Do you sell generators and turbines?

Yes. J&J publishes diesel and natural gas generator offers, gas turbine packages and steam power plant positions. Each listing states ratings, condition, scope and availability qualifications. Send the J&J reference, MW, voltage, frequency, fuel, quantity and required date for a current written quotation.

Can I request equipment that isn’t listed?

Yes. J&J supplies power transformers, diesel and natural-gas generators, and gas and steam turbines beyond the public inventory. Submit your MVA or MW, voltages, quantity, project location and required date, or call Tommy Marco at 346-276-9540. Availability and technical fit are confirmed for each candidate.
