Purchase, inspection and delivery
Pricing is available from Transformer Traders on request. The stated delivery basis is EXW South America, with equipment offered as-is, where-is. The buyer is responsible for loading, export/import clearance, freight, insurance, duties and taxes unless a separate written scope provides otherwise.
Inspection is available by appointment before purchase. Specifications are owner-represented and should be verified during inspection and against unit-specific documents. The offer may be modified or withdrawn without notice; the units remain subject to prior sale until a purchase agreement is executed and the required deposit is received. No binding contract arises from this listing.
Technical records to confirm
The supplied summary does not identify the manufacturer, serial numbers, manufacturing year, tap arrangement, impedance, dimensions or shipping weights. Request nameplates, general arrangement drawings, test reports, accessory schedules and shipment data. The cooling notation ODTF1 / ODAF2 and the listed bushing description are reproduced as supplied, without interpreting or correcting them.
