What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete 2,500 kVA transformers anywhere in North Carolina. This page covers nameplate checks, shipping weight, testing and removal for plant engineers, utility asset managers, facility directors and demolition crews handling a substation unit.
Whether the transformer served a data center, a mill or a utility station, assessment starts with its voltage pairings, condition records and access around the tank.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 2,500 kVA | up to 34.5 kV | Liquid or dry |
| 3-phase | 50 - 20,000 kVA | 46 kV | Liquid or dry |

Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
Reading 2,500 kVA
A 2,500 kVA nameplate describes apparent power, not tank weight or usable kilowatts under every load. On a three-phase unit with a 480-volt secondary, rated secondary current is about 3,007 amperes.
That current helps explain the substantial secondary bus and termination compartment.
Check whether 2,500 kVA is the base cooling rating or a higher rating reached with fans. Photograph the complete nameplate, including ONAN or ONAF markings, impedance, winding connections and temperature rise.
A missing fan bank can change how the recorded rating should be interpreted.
Local reality
Where this size sits in the state's industrial base
In North Carolina, a 2,500 kVA substation unit can serve a data center electrical block, a mill process area or a utility station.
Its removal may involve more than the tank: secondary bus, protective relays and grounding connections can belong to separate project scopes.
For a Piedmont mill shutdown or a Research Triangle facility renovation, establish ownership before discussing removal. A transformer behind the fence may still belong to the serving utility. Asset tags, retirement paperwork and the one-line diagram help distinguish customer equipment from utility property.
Around the site
What it weighs
Shipping weight for a 2,500 kVA transformer is roughly 16,000 to 26,000 pounds. Construction changes the number: liquid volume, tank dimensions, radiator banks and termination compartments all matter.
Use the manufacturer's weight record rather than estimating from the kVA rating alone.
A nameplate may list total weight, oil weight and untanking weight separately. Those figures describe different handling conditions. Before a North Carolina pickup, confirm whether the stated shipping weight includes liquid, radiators and loose accessories, and record any components already removed from the tank.
Where it sits
Moving it
Handling planning for this size can involve a 60-ton crane and a lowboy with a jeep and booster. The crane's nominal capacity is not its capacity at every radius.
The lift contractor must check actual weight, boom configuration, outrigger support and clearance above bushings.
Walk the route from the transformer pad to the loading position before mobilization. At a North Carolina mill, narrow gates, pipe racks and buried utilities can control crane placement.
Verify lifting lugs, spreader bar requirements and trailer dimensions before disconnecting radiators or disturbing tank fittings.
On the ground
Voltage pairings
A 2,500 kVA unit might carry a 13,800-volt primary and a 480Y/277-volt secondary, but the rating alone does not establish either voltage. Read the nameplate and tap chart.
Confirm whether the primary termination uses exposed bushings, cable boxes or separable connectors inside a compartment.
A utility station unit with a 4,160-volt secondary requires a different assessment from a 480-volt mill transformer. Record winding connections, neutral terminals, BIL and tap position.
Photographs of the secondary throat and primary bushings help identify the actual arrangement without assuming it from site use.
Local reality
What we test
For a de-energized 2,500 kVA transformer, useful electrical checks include turns ratio, winding resistance and insulation resistance. Test selection depends on condition and safe access.
Compare results across phases and against prior reports; one isolated reading does not establish whether the core and windings remain serviceable.
On liquid-filled units, review dissolved gas analysis, moisture and dielectric test reports when available. A failed mill transformer with relay-trip records, leaking radiator gaskets or cracked bushings needs documented fault history.
Sampling and electrical testing require qualified personnel, isolation and the owner's authorization before work begins.

How we value it
Our assessment of a 2,500 kVA transformer considers documented condition, voltage pairings, winding material and completeness. An intact substation unit with readable records differs from a fire-damaged tank with missing bushings.
Nameplate photographs and maintenance reports establish what remains, rather than relying on an asset-list description.
Removal conditions also shape the assessment. A 26,000-pound unit beside a clear loading lane presents different work from one enclosed behind mill walls. Identify oil status, PCB documentation, disconnected bus and ownership records early.
These details define handling responsibilities and prevent assumptions about the removal scope.

Questions
Straight answers
Equipment types
Can you buy a failed 2,500 kVA transformer?
Yes. We buy failed 2,500 kVA transformers in North Carolina as well as used, surplus and obsolete units. Provide the nameplate, fault history and photographs of damaged bushings or tank areas.
Service area
Does every unit require a 60-ton crane?
No. A 60-ton crane is a planning reference, not a universal requirement. A 2,500 kVA transformer's roughly 16,000-to-26,000-pound shipping weight must be checked against lift radius, rigging and site conditions. The lift contractor selects equipment using the crane load chart and verified weight.
Payment
What paperwork helps assess a mill transformer?
Start with the 2,500 kVA nameplate, ownership or retirement records, one-line diagram and maintenance reports. Include PCB documentation for liquid-filled equipment and any fault investigation. A component list should identify removed radiators, fans or bushings so the recorded shipping weight can be checked.

Voltage pairings: what should a seller know?
A 2,500 kVA unit might carry a 13,800-volt primary and a 480Y/277-volt secondary, but the rating alone does not establish either voltage. Read the nameplate and tap chart.
