Compare transformer manufacturers and generation models
Transformer records include ABB / Hitachi, Royal SMIT, Georgia Transformer, Kolektor ETRA, Prolec GE and other individually identified manufacturers. Generation offers include Caterpillar diesel sets, Wärtsilä and MWM packages, GE TM2500, LM2500 and LM6000 turbines, and Siemens equipment. Manufacturer and model names identify the offered equipment; no OEM dealership or affiliation is claimed.
New surplus and used power equipment for sale
Unused surplus is separate from previously operated equipment. Rebuilt or refurbished units need a documented work scope and matching tests; a future manufacturing or refurbishment position has a completion milestone. Compare these details with the individual record before choosing equipment.

Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Where can I buy industrial power equipment?
J&J Transformers LLC serves projects nationwide from Sugar Land, Texas. Email tommy@jjtransformers.com or call Tommy Marco at 346-276-9540 for the exact equipment record, price and written availability. Equipment locations and delivery are confirmed for the individual offer.
Does a sales category mean every model is in stock?
No. Published records describe the actual offered equipment and its dated evidence. An unlisted rating, switchgear lineup, breaker model or complete package requires a separate current quotation.
