69 kV source and output arrangements
A dedicated 69/34.5 kV transformer and a 230 kV autotransformer with a 69 kV winding choice are different candidates. Review the source, output, winding connection and permitted duty before requesting a price.
Prepare a 69 kV transformer buying request
Define whether 69 kV is the incoming system, generator export or required output winding. A reconnectable 230/115/69 kV autotransformer record has a different winding arrangement from a dedicated 69 kV transformer. Compare the complete voltage schedule and duty before requesting a price.

| Buying requirement | What to compare |
|---|---|
| 69 kV GSU transformers for sale | For a 69 kV generator step-up transformer, identify the generator voltage, required continuous MVA and grid-side connection. A 69 kV secondary on a larger autotransformer is a separate winding duty; compare the actual power-flow requirement. |
| 69 kV substation transformers for sale | For a 69 kV substation transformer, state the incoming system voltage and the required 34.5 kV, 13.8 kV, 12.47 kV or other load-side voltage. Review the exact available ratio rather than assuming every 69 kV unit has the same secondary. |
| 69 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. |
Which 69 kV transformer opportunities are listed?
The following 4 public records are open for inquiry. A listing may contain multiple units or offered positions. Sold and committed equipment is excluded, and submitted schedule quantities still require individual identity confirmation.
What should a 69 kV transformer request include?
Provide base and forced-cooled MVA, exact high- and low-side voltages, maximum system voltage, winding connections, BIL, impedance with its MVA and tap basis, taps, cooling, losses, terminals, accessories, quantity, site, documents, acceptable condition, and needed-on-site date.
- State whether the duty is substation, collector, GSU, network, industrial, or autotransformer service.
- Identify grounding, neutral duty, tertiary requirements, regulation, fault cases, and parallel-operation constraints.
- Include the one-line and existing-unit nameplate for replacement projects.
Is the public ABB 230/69 kV autotransformer a 69 kV high-side transformer?
No. Its reviewed nameplate describes a 230 kV autotransformer with a common winding reconnectable for 69 or 115 kV service and a 13.5 kV delta tertiary. The complete one-line and studies must confirm whether that construction matches the project.
Autotransformer winding duties, common and series winding currents, tertiary function, regulation, grounding, protection, and fault performance differ from a conventional two-winding transformer. A matching 69 kV number alone does not establish suitability.
How can an owner offer a 69 kV transformer?
Submit the OEM, serial, nameplate, MVA stages, complete ratio, BIL, impedance, vector, taps, condition, present country and state, ownership or transfer authority, photos, drawings, tests, included scope, and loading requirements.
Public listings are represented opportunities, not reserved or guaranteed stock. Seller authority, serial identity, present condition, exact location, availability, price, included scope, and delivery require current written confirmation and remain subject to prior sale.
Request price, availability and delivery
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com. Include the listing ID if you have one, MVA, exact voltage ratio, quantity, acceptable condition, site and required delivery date. J&J serves U.S. projects nationwide from Sugar Land, Texas.
- Choose new or unused surplus, used, rebuilt or reconditioned equipment; condition is stated for the specific offered unit.
- Request photos, nameplate, drawings, available tests, included accessories and inspection terms.
- Confirm price, freight or delivered scope, loading, warranty, payment terms and the agreed delivery milestone in writing.
69 kV step-down transformer requirements
For a 69 kV step-down request, provide both source and output winding voltages, required continuous MVA, quantity and project date. Compare the candidate's actual operating-direction limits, winding connections, grounding, taps, impedance, insulation and installation interfaces. The voltage page remains a screening route; the step-down hub explains duty and quotation evidence.
69 kV-class transformer sale and quotation requirements
For a 69 kV-class transformer inquiry, identify both winding voltages, the required continuous MVA and the proposed step-down, GSU, substation or autotransformer duty. This voltage category helps organize a purchase request; it does not establish stock at every rating or automatically qualify a candidate for the system.
- Specify condition acceptance, quantity, winding connections, grounding, taps, impedance, installation limits and needed-on-site date.
- Match the actual second winding voltage and duty-specific cooling rating; the high-voltage class alone does not identify the required transformer.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
How do I request a 69 kV transformer price and delivery quote?
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com with the actual source and output voltages, continuous MVA, duty, quantity, site and required date. Identify condition preferences and include a nameplate, one-line or specification when available. The quotation confirms the proposed unit, records, accessories, allocation and transport scope.
Where can I buy 69 kV transformers?
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com. Review the current 69 kV transformer equipment page or send your specification for a different GSU or substation requirement. Current availability, price and delivery are confirmed in writing.
Which 69 kV transformers are offered for sale?
Published 69 kV records include Virginia Transformer, 21/28/35 MVA, 69/12.47 kV; Virginia Transformer, 20/26.66/33.33 MVA, 69/12.47 kV; Virginia Transformer, 36/48/60 MVA, 69/34.5 kV; Virginia Transformer, 100 MVA, 69/34.5 kV. Compare each unit's listed condition and exact winding duty, then request current allocation and the matching technical package.
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.
Is a 230/69 kV autotransformer public?
Yes. One ABB nameplate-documented record describes reconnectable 69 or 115 kV common-winding service. Condition, quantity, scope, and availability require written confirmation.
Can a 230/69 kV autotransformer replace a two-winding 69 kV transformer?
Do not assume so. The responsible engineering team must approve winding construction, grounding, impedance, taps, protection, fault duty, tertiary use, and every interface.
Can J&J supply 69/34.5 or 69/13.8 kV?
J&J can screen either requirement when exact MVA, ratio, duty, vector, BIL, impedance, taps, condition acceptance, site, records, quantity, and required date are supplied.
Can an owner submit a 69 kV transformer?
Yes. Direct owners and properly authorized representatives can email tommy@jjtransformers.com with the equipment details they have.
Is availability guaranteed?
Public listings are represented opportunities, not reserved or guaranteed stock. Seller authority, serial identity, present condition, exact location, availability, price, included scope, and delivery require current written confirmation and remain subject to prior sale.
