5–90 MVA substation transformers for sale
J&J accepts 5–90 MVA substation transformer requirements and publishes individual equipment offers within this range. Tell us whether the requested MVA is the base or forced-cooled rating. Each available candidate retains its actual winding voltages, cooling stages and stated condition; every size in the table is a quote requirement, not a claim of stock at that exact rating.

Current transformer records within the 5–90 MVA range
These candidates are selected using the highest published primary cooling-stage rating, excluding tertiary ratings. A 40/53.3 MVA transformer is shown with its actual cooling stages; it is not relabeled as an exact 50 MVA unit. Review any condition questions, winding duty and dated release basis in the listing.

A transformer purchase or a complete substation package?
For a complete substation requirement, send the equipment schedule covering the transformer, breakers, disconnects, switchgear, protection and controls. Individual transformer records cover only their stated equipment and accessories. Design, site works, installation and commissioning are included only when expressly quoted.
Request a 5–90 MVA transformer quote
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com for specifications, price, current availability and delivery. Include MVA and cooling stages, voltage ratio, phase, frequency, winding connection, taps, impedance, insulation, quantity, destination and needed-on-site date.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Does J&J have every size from 5 to 90 MVA available?
J&J publishes specific offers in this range and accepts other size requirements for quotation. No stock at every exact rating is claimed. Review the actual offered ratings and request current written availability.
Can I request a 5, 10, 20, 30, 50, 75 or 90 MVA substation transformer?
Yes. Send the required MVA basis, winding voltages, condition, quantity and delivery date. Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com for specifications, price, current availability and delivery. A larger nameplate cooling stage alone does not establish a technically suitable replacement.
Are 5–90 MVA complete substations available?
A complete substation package requires a separate equipment schedule and written availability for the included components. A transformer offer does not establish a complete ready-to-install substation.
