Details to confirm for this listing
- Final unit-specific nameplate, approved revision, tested impedance/losses and final tertiary arrangement
- Conductor, OLTC switch specification, complete accessories, current photos and preservation or manufacturing progress
Technical highlights
- Supplied design data sheet; final unit-specific nameplate and FAT pending.
- Ask J&J for the included U.S.-port shipping, commissioning and manufacturer warranty scope in the written offer.
- Modifications can be reviewed before completion; feasibility, cost and schedule impact require OEM confirmation.
- Any warranty provider, scope, transfer eligibility, start date and commissioning boundary must appear in the written quotation.
- Design basis: ONAN/ONAF1/ONAF2, 60 Hz, 65 C temperature rise; grounded-wye high and low sides.
- HV OLTC design range ±10%; preliminary 13.8 kV open-delta tertiary. Final unit-specific configuration requires approval.
- Design H-X impedance: 9% at a 125 MVA base. This is a design-sheet value, not a final tested result.

Photos, matching records and inspection arrangements are coordinated through J&J.
Request written termsCheck this transformer against your project
Compare the complete winding arrangement and condition evidence before requesting a quote. A matching voltage ratio alone does not establish suitability.
- Match MVA, voltage, impedance, taps and winding connections
- Review seven transformer condition risks before purchase
