Review the 525/69 kV Royal SMIT candidate
The public equipment record includes the supplied nameplate, outline drawing and factory test report. It distinguishes 400 MVA step-up rating from the 250 MVA step-down limit. Ask for unit-specific condition, matching records, inspection access and the included equipment schedule.
500 kV GSU and substation transformers for sale
J&J accepts 500 kV power transformer, generator step-up and substation transformer requirements. 500 kV system projects requiring review of the actual transformer nameplate, insulation and operating duty. Email your one-line, MVA, voltage ratio, quantity and needed-on-site date for the relevant equipment records and quotation.

| Buying requirement | What to compare |
|---|---|
| 500 kV GSU transformers for sale | For a 500 kV-class GSU requirement, compare the actual nameplate and project specification. The Royal SMIT candidate has 525/69 kV windings and 240/320/400 MVA cooling stages; its 400 MVA rating is for step-up duty, with separate step-down limits. |
| 500 kV substation transformers for sale | For a 500 kV substation requirement, review the Royal SMIT 525/69 kV candidate's 250 MVA maximum step-down duty. The 525 kV nameplate is retained in every equipment record; a 500 kV system voltage does not by itself establish compatibility. |
| 500 kV substation equipment or a complete package | Specify the transformer, breakers, switchgear, disconnects, protection and controls required. Included equipment and site work are defined in the quotation; an individual transformer listing is not a complete substation package. |
What is needed to review a 500 kV substation or GSU requirement?
Send the utility or project specification and one-line with the required MVA, operating direction, low-side voltage, winding connections, insulation levels, impedance, tap range, quantity and delivery date. The project engineer and utility review the actual nameplate and factory records; no automatic 500 kV compatibility is claimed.

Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Where can I buy a 500 kV-class transformer?
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com to review current high-voltage equipment candidates or submit a different requirement. The published Royal SMIT candidate is nameplated 525/69 kV, and technical fit for a 500 kV system requires project review.
Is a 525 kV transformer automatically suitable for a 500 kV system?
No. Check winding voltages, taps, insulation, operating direction, MVA duty, protection and utility requirements against the unit-specific records.
Can the Royal SMIT transformer supply 400 MVA in step-down duty?
The published nameplate limits step-down duty to 250 MVA. Do not use the 400 MVA step-up rating as a 400 MVA step-down capacity claim.
Is a substation transformer the same as a complete substation for sale?
A substation transformer is one piece of equipment. A complete substation package has a defined equipment schedule that may include breakers, disconnects, switchgear, protection and controls. Ask J&J for the exact included scope; site design, installation and commissioning are included only when expressly quoted.
