Sell your surplus cast coil transformers.
Medium voltage only. Never a 480V primary.
Get an offerWhat we pay for and why
Value on a cast coil transformer comes down to kVA, primary voltage, winding metal, age, and whether it still tests. New surplus on the skid is worth the most. Failed units are worth their metal and oil.

What drives the number on this unit
ABB, Schneider, and Eaton cast coil resells into data center and hospital work. The brand on the resin is a price term.
Cracks, tracking, or discoloration on the cast windings are what an inspection looks for. Close-up photos of each coil face help the offer.
Redundant-pair installations produce matched takeouts, and pairs sell better than singles.
Most cast coil comes out of critical facilities that ran them at half load. If you have loading data, send it; it is worth money.
Reading the nameplate
Nameplate is on the enclosure frame. Photograph it plus each cast coil face through the enclosure. These units are bought heavily on visuals, so more photos is genuinely more money.
Freight and rigging
Comparable to MV dry-type but denser: a 1500 kVA pair can be 15,000 pounds of freight. Indoor removal from electrical rooms and penthouses is normal; send the route and we bring the plan.

FAQ
Yes. The core, windings, tank steel, and oil all carry value. Tell us the failure mode if you know it.
Send the other two photos and whatever you know. Illegible nameplates route to a slower queue, but the lead still gets a call.
No. Dry-type units have no oil and no PCB exposure. We skip that step entirely.
We do. Flatbed for most units, lowboy or crane for larger substation gear. Tell us if the unit is truck accessible.
Not automatically. Depends on depth and location. Send close-ups; some damage repairs, some re-rates the unit, some sends it to material value. We tell you which before the offer.
Because a cast coil from a climate-controlled data hall and one from a foundry mezzanine are different animals at the same nameplate. The environment is part of the appraisal.
