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
What 50,000 kVA means on a nameplate
A 50,000 kVA nameplate rating equals 50 MVA of apparent power. It does not establish the real-power output without the load power factor.
Read the complete rating plate, including frequency, winding voltages, cooling designations, temperature rise, and impedance, before identifying the unit for a buyer.
Cooling stages can give one transformer several MVA ratings. Determine whether 50,000 kVA describes the base cooling stage or a stage requiring fans and oil pumps.
Nameplate photographs should show each rating line clearly, along with the serial number and manufacturer, rather than just the largest figure.
Local reality
Where 50,000 kVA units are used in North Carolina
A typical application is a large power transformer serving a 230 kV or 345 kV substation. In North Carolina, evaluation starts with the actual station one-line diagram.
The stated MVA alone cannot establish whether the unit served transmission, an industrial interconnection, or another station arrangement.
Retirement paperwork from a Piedmont industrial site or a utility station near the coast should identify the asset owner, station designation, and release authority. A demolition contractor may control the work area without owning the transformer.
That distinction must be settled before removal engineering proceeds.
Around the site
Weight and dimensions in practice
Shipping weight for a 50,000 kVA unit is roughly 320,000 to 480,000 pounds. Treat that band as an initial planning reference, not a lifting instruction.
The certified outline drawing must identify the transport configuration and distinguish tank weight from oil, bushings, radiators, and other removed components.
Measure the transport envelope after accounting for detached bushings, conservator equipment, and radiator banks. A North Carolina station gate can pass the bare tank yet block a loaded transporter.
Record overhead conductors, turning space, pad elevation, and the distance between the transformer foundation and the loading point.
Where it sits
Handling a 50,000 kVA unit
Rail handling belongs in the initial removal plan for a transformer in this weight class. The move is a months-long engineering exercise involving railcar selection, load securement, route review, and terminal access.
A nearby rail line does not establish that a usable siding or unloading location exists.
Engineers must verify jacking pads, lifting points, center of gravity, and allowable tank loads before selecting rigging. At a North Carolina substation, the plan also needs ground-bearing checks and electrical clearances.
Oil draining, bushing removal, blanking plates, and dry-gas protection require a documented sequence tied to manufacturer instructions.
On the ground
Voltage and phase combinations
The 50,000 kVA rating does not define a voltage ratio or phase arrangement. A unit associated with a 230 kV or 345 kV station needs its complete winding data reviewed.
Record high-side, low-side, and tertiary ratings, along with connection diagrams and any neutral terminal details.
For three-phase units, phase displacement and winding connections affect suitability for another station duty. For a single-phase unit, establish whether 50,000 kVA is the individual rating rather than a bank rating.
Tap-changer range, insulation levels, and system frequency must come from the nameplate and supporting drawings.
Local reality
Condition and testing
A failed 50,000 kVA transformer needs more than a description of the trip event. Relay targets, fault records, dissolved-gas results, and inspection photographs help distinguish a bushing failure from winding damage.
Record tank distortion, pressure-relief operation, oil loss, and any evidence of fire around the terminal connections.
For an intact retired unit, provide dated winding-resistance, ratio, insulation, and power-factor test reports when available. Include tap-changer maintenance records and oil laboratory reports, including PCB documentation.
Testing a 230 kV or 345 kV asset requires qualified personnel, isolation, grounding, and a procedure appropriate to its condition.
Around the site
What a 50,000 kVA unit is worth to a buyer
To a buyer, the useful distinction is whether this 50,000 kVA asset supports further service evaluation, component recovery, or material recovery. Voltage compatibility, winding condition, oil documentation, and complete drawings shape that assessment.
A readable nameplate and verified ownership establish what equipment can actually be considered.
Removal constraints can change the practical disposition of a 320,000 to 480,000 pound transformer. An accessible rail loading point, approved outage window, and sound jacking pads support a workable plan.
Missing transport drawings, uncertain oil status, or a foundation surrounded by energized equipment require investigation before acceptance.

Questions
Straight answers
Equipment types
Can you buy a failed 50,000 kVA transformer?
Yes. Transformer Buyers NC buys failed 50,000 kVA units as well as retired and surplus equipment. Evaluation needs the nameplate, failure description, photographs, oil records, and ownership documentation. A ruptured tank or damaged bushing also changes the containment and removal plan.
Service area
Does a 50,000 kVA transformer require rail transport?
Rail is a primary planning consideration at roughly 320,000 to 480,000 pounds shipping weight. The final transport method requires engineering review of the actual configuration, loading access, and route. Rail transport still requires a workable transfer plan between the station foundation and the railcar.
Payment
Which records help evaluate a retired substation unit?
Provide the nameplate, certified outline drawing, winding diagram, latest electrical tests, oil reports, and tap-changer service records. For a 230 kV or 345 kV station asset, include the one-line diagram and release authorization. Transport drawings should identify removed components and the verified shipping weight.

Voltage and phase combinations: what should a seller know?
The 50,000 kVA rating does not define a voltage ratio or phase arrangement. A unit associated with a 230 kV or 345 kV station needs its complete winding data reviewed.
