Technical selection
Buying a 138/13.8 kV transformer
Send the required MVA at each cooling stage, winding connections, impedance and its rating base, tap-changer requirements, frequency and terminal arrangement. For 138/13.8 kV candidates with multiple listed voltages, confirm reconnection details and which configuration the test reports cover. Do not assume a tertiary voltage or simultaneous operation from a slash-separated field.
Compare condition and documentary evidence
For new/unused equipment, confirm storage and preservation, factory records, completeness and any transferable warranty. For pre-owned equipment, request operating and maintenance history, removal details, oil and electrical testing, and documented repairs. A catalog condition label does not establish a remaining service life or test result.
Request the unit-specific package
Ask for the nameplate, winding diagram, general arrangement, available tests, accessory list, shipping configuration, weights and oil information. List missing records and proposed inspections in the purchase review.
Read the related procurement guideMake delivery part of
the equipment decision.
Confirm origin and destination, site access, preparation, oil handling, accessory shipments, transport permits, offloading and installation scope. Agree whether a quoted date means factory release, pickup, site arrival or readiness for commissioning.
Discuss turnkey delivery and installationWhere can I buy this transformer configuration?
Contact Transformer Traders using the equipment ID from this collection or submit your specification. We review published inventory and additional sourcing opportunities, with price, availability and scope confirmed in writing.
Can an available unit be delivered immediately?
Catalog availability is not a dispatch commitment. Document review, inspection, preparation, loading, permits and receiving-site readiness determine the delivery plan for the individual unit.
What if none of the listed equipment fits?
Send the mandatory ratings, winding voltages, physical constraints, quantity and deadline. We can review other surplus and pre-owned sources or discuss a new-build option. Engineering acceptance remains project-specific.
