What we buy
Ranges we buy on this page
This page covers the identification, inspection and removal of 13.8 kV class transformers at North Carolina generating stations and industrial facilities. It is written for plant engineers, utility asset managers, facility directors and contractors planning equipment retirement.
Transformer Buyers NC buys used, surplus, failed and obsolete units across the state. Nameplate voltage, insulation level, service history and the route from the foundation to the truck guide the assessment.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 25 - 20,000 kVA | 13.8 kV Class | Liquid or dry |
| 3-phase | 75 - 10,000 kVA | up to 34.5 kV | Liquid-filled |

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 13.8 kV Class means
The 13.8 kV class is a utility and industrial standard that sits alongside 12.47 kV. Read the actual winding voltages on the nameplate rather than relying on the switchgear label.
A unit serving a 13.8 kV bus may have several secondary windings.
Insulation commonly includes a basic impulse insulation level, or BIL, around 125 kV. Bushings can be interchangeable with the 12.47 kV family, but fit alone does not establish suitability. Confirm the bushing drawing, current rating, creepage distance and terminal arrangement before substitution.
Local reality
North Carolina installations
Generating station auxiliaries are a familiar North Carolina application for 13.8 kV equipment. These transformers support plant service circuits, with winding arrangements determined by the station design.
Retirement records should identify the unit’s former duty, not merely describe it as a station transformer.
Large industrial services also use 13.8 kV, including facilities with their own medium-voltage distribution. At a North Carolina mill or manufacturing campus, the transformer may sit behind an indoor switchgear lineup or inside a fenced yard.
That location shapes isolation and removal planning.
Around the site
Clearances that decide the rigging
A 13.8 kV transformer’s tallest obstruction may be a bushing, conservator or cable box rather than the tank. Measure the complete assembly against the doorway, overhead pipe rack and crane path.
Separate electrical approach limits from the physical clearance needed to lift isolated equipment.
Radiators can extend beyond a North Carolina plant’s original equipment access opening. Record tank dimensions, removable attachments and lifting-lug locations before selecting a spreader bar.
Use the manufacturer’s lifting instructions; radiator headers and bushing flanges are not substitutes for designated lifting points.
Where it sits
Field testing
For a retired 13.8 kV unit, existing test reports often explain more than an exterior photograph. Useful records include insulation resistance, winding resistance and turns-ratio results, with tap positions and test conditions recorded.
Compare results with earlier readings and the manufacturer’s acceptance criteria.
Oil-filled 13.8 kV transformers may also have dissolved gas analysis and moisture reports. A failed unit needs the trip report, relay targets and any evidence of tank pressure or bushing flashover.
Testing belongs with qualified personnel after isolation, absence-of-voltage verification and appropriate grounding.
On the ground
Moving high-voltage equipment
Moving a 13.8 kV transformer starts with verified shipping weight, not an estimate from tank size. The nameplate or outline drawing should distinguish assembled weight from oil and accessory weights.
Lowboy selection depends on loaded height, axle loading and the North Carolina haul route.
Before loading at a generating station, document which 13.8 kV bushings, radiators and cable boxes remain attached. Removed openings need suitable covers, and loose accessories need identification.
Confirm oil containment, transport orientation and securement requirements with the carrier and the manufacturer’s handling instructions.
Local reality
Valuation notes
Assessment of a 13.8 kV transformer starts with its nameplate: kVA, winding voltages, phase count, impedance, cooling designation and tap range. BIL and connection diagrams matter too. A legible photograph prevents confusion between a 13.8 kV primary and a different winding designation.
Condition records distinguish a serviceable 13.8 kV unit from one retired after an internal fault. Include leak locations, missing bushings, damaged radiators and any oil analysis. For older North Carolina equipment, provide PCB documentation where applicable rather than assuming age establishes fluid classification.
Around the site
Next steps
For a North Carolina 13.8 kV transformer review, assemble nameplate photographs, overall views and the latest available test reports. Include the site address, ownership contact and retirement status. Photographs should show all sides of the tank, terminal compartments and the access route.
Transformer Buyers NC buys 13.8 kV units statewide, including failed and obsolete equipment. Before removal planning, identify who controls switching, disconnection and site access. Plant shutdown dates, crane restrictions and documentation of authority to release the transformer help establish a workable pickup sequence.

Questions
Straight answers
Equipment types
Are 13.8 kV and 12.47 kV transformers interchangeable?
Not automatically. The two families can share interchangeable bushings, but transformer winding voltages, tap ranges, insulation ratings and connections still govern application. For a 13.8 kV unit, provide the nameplate and connection diagram rather than treating similar external hardware as proof of compatibility.
Service area
Can you buy a failed 13.8 kV transformer?
Yes. Transformer Buyers NC buys failed 13.8 kV transformers across North Carolina. Document the failure, including relay operation, visible bushing damage, oil leakage or tank deformation. State whether the unit remains connected and provide available oil reports and incident records.
Payment
What records help plan a generating station removal?
For a 13.8 kV generating station auxiliary transformer, gather the outline drawing, shipping weight, lifting instructions and isolation plan. Include access restrictions and photographs of overhead obstructions. Identify the station representative responsible for confirming disconnection and authorizing release before rigging begins.
Logistics
Field testing: what should a seller know?
For a retired 13.8 kV unit, existing test reports often explain more than an exterior photograph. Useful records include insulation resistance, winding resistance and turns-ratio results, with tap positions and test conditions recorded.
