Buying several transformers or reviewing an exact ratio?
For a multi-unit order, specify each electrical configuration, accepted condition and delivery phase. Start with the current equipment records, then request the identity, documents, allocation and quote scope for each proposed unit.
Prepare a 161 kV transformer buying request
Review the documented 161/34.5 kV equipment record against the actual project specification. State continuous MVA, cooling duty, winding connections, taps, quantity and the required site date. A 138 or 230 kV listing is a separate voltage-class alternative requiring explicit project review.
Which 161 kV transformer opportunities are listed?
The following 1 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.
Which 161/34.5 kV transformer is publicly documented?
The public inventory includes a Siemens Energy transformer rated 63/84/105 MVA, 161/34.5 kV, with a 13.8 kV additional winding, ONAN/ONAF1/ONAF2 cooling, and a December 2022 nameplate.
The reviewed nameplate supports the ratings and configuration summary. J&J separately confirmed that the unit is available, brand new and never used. Confirm the included loose-shipped parts, technical fit and delivery scope with the quotation.
What must match besides 161/34.5 kV and 105 MVA?
Confirm every winding duty, vector and grounding, 13.8 kV winding purpose and rating, impedance and base, BIL, OLTC range and controls, losses, cooling, terminals, accessories, dimensions, weights, fluid, sound, site conditions, transport configuration, and required standards.
- Use the project one-line and studies to confirm whether the 13.8 kV winding is required and how it will be operated.
- Compare the actual tap range and regulation duty with source-voltage and load cases.
- Confirm field assembly, oil processing, testing, protection, and energization scope before relying on a delivery milestone.
How should another 161 kV requirement be submitted?
Send the required MVA stages, exact high-, low-, and tertiary voltages, application, BIL, impedance and basis, vector, taps, cooling, losses, quantity, project state, destination, acceptable condition, available documents, and needed-on-site date.
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.
161 kV step-down transformer requirements
For a 161 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.
161 kV-class transformer sale and quotation requirements
For a 161 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 161 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.
Does the Siemens 161 kV unit have a tertiary?
The reviewed nameplate identifies a 13.8 kV additional winding. Its intended duty and complete ratings must be confirmed from the technical package.
Where is the 161 kV transformer?
It is represented as located in the United States. The exact storage location is disclosed after project qualification.
Is the transformer new or used?
The Siemens Energy 63/84/105 MVA 161/34.5 kV transformer is brand new and never used. J&J confirmed its condition and availability on September 24, 2026. Subject to prior sale; final allocation and delivery terms are confirmed in writing.
Can J&J supply another 161 kV transformer?
Yes. Submit exact MVA, ratio, duty, BIL, impedance, vector, taps, cooling, condition acceptance, location, records, quantity, and needed-on-site date.
Who approves technical suitability?
The project owner and responsible engineering team approve system studies, protection, transport, installation, testing, and operation. J&J is not the engineer of record.
Can I request several transformers with different voltage ratios or MVA ratings?
Yes. Send quantity per configuration, winding voltages, continuous MVA, accepted condition and required delivery phase to Tommy. The quotation identifies the actual unit, documents, allocation and included scope for every position. Identical-unit and parallel-operation requirements need explicit review.
