Sell three-phase transformers with complete specifications.
Three-phase is a broad electrical category, not a complete equipment description. The configuration, enclosure, cooling method and voltage relationship identify the actual resale application.
A three-phase listing should include kVA or MVA, primary and secondary voltage, frequency, impedance, taps and winding connection. Enclosure, cooling class, temperature rise and application further narrow the market.
Photograph the complete nameplate straight on, without glare. Add full-unit views and close-ups of terminals, cabinets, radiators, gauges or damage when safely accessible.

02
Avoid vague inventory descriptions
Descriptions such as ‘480 transformer’ or ‘three-phase can’ leave out the information a buyer needs. A short, accurate specification line—supported by the nameplate—makes the inquiry searchable, comparable and easier to act on.
03
Connection and voltage must be unambiguous
Three-phase equipment can be configured for many voltage relationships and winding connections. Write the primary and secondary exactly as shown on the nameplate. If the plate includes a vector diagram, photograph it clearly rather than translating it from memory.
Taps, dual-primary arrangements and multiple secondary windings can change the available applications. Include those details so the equipment is not incorrectly grouped with a superficially similar unit.
04
Group matching units carefully
A lot should be called matching only when the manufacturer, model, electrical ratings and essential construction are the same. Serial numbers and manufacture dates may still vary. Photograph each nameplate and tie every photo set to a unit number so differences are visible.
Never open energized equipment or move, drain or dismantle a transformer solely for an inquiry. Use qualified personnel and applicable site procedures.
Straight answers
Questions sellers ask.
These answers are intentionally specific and conditional. Final terms depend on the equipment and written agreement.
Do you buy 480-volt three-phase transformers?+
We review many three-phase configurations, but 480 volts may be the primary or secondary voltage. Send the full nameplate to confirm the actual configuration.
Can multiple matching units be reviewed together?+
Yes. Include the quantity and identify whether all units share the same manufacturer, ratings, condition and location.
