What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed, and obsolete 7,500 kVA transformers anywhere in North Carolina. This page covers equipment identification, inspection records, and removal planning for plant engineers, utility asset managers, facility directors, EPC contractors, demolition crews, and bankruptcy trustees.
A unit in this class commonly serves a utility substation or large industrial captive station. Its roughly 48,000 to 75,000 pounds makes removal a planned heavy-haul project.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 7,500 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
The 7,500 kVA class
A 7,500 kVA nameplate identifies a 7.5 MVA apparent-power rating, not a fixed physical size. Cooling stages matter: an ONAN/ONAF unit may carry separate ratings for natural and forced-air operation.
Photograph every rating line rather than reporting only the largest number on the plate.
At a North Carolina substation, this class may have a conservator, separate radiator banks, or a sealed main tank. Those arrangements change disassembly and shipping preparation. Record the manufacturer, serial number, impedance, cooling designation, and year before drawings or maintenance files leave the site.
Local reality
Typical North Carolina applications
Utility substations use 7,500 kVA power transformers to connect a higher-voltage circuit with local distribution equipment. In North Carolina, a retired unit may remain inside an energized yard.
Removal planning must distinguish the isolated transformer bay from neighboring buses, control cables, and grounding connections.
Large industrial captive stations at paper mills, chemical plants, and manufacturing campuses can use this rating to feed plant distribution.
A shutdown near the Cape Fear River or in the Piedmont may leave disconnected equipment behind fenced switchgear, with restricted access for cranes and trailers.
Around the site
Shipping weight and footprint
Shipping weight is roughly 48,000 to 75,000 pounds for this class, but the actual lifting weight must come from equipment records. Determine whether the stated figure includes oil, radiators, bushings, and loose accessories.
An operating weight cannot automatically serve as a prepared shipping weight.
Measure the tank, radiator projection, bushing height, and base dimensions before selecting a trailer. At a North Carolina industrial station, the narrow point may be a gate or pipe rack rather than the transformer pad.
Record transport dimensions after any planned removal of external components.
Where it sits
Rigging and load-out
A 150-ton crane is a planning reference for handling a 7,500 kVA transformer, not a guaranteed lift selection. The crane contractor must check radius, boom configuration, ground bearing, and rigging weight.
Verified lifting lugs and a suitable spreader bar keep slings away from bushings.
The move is a project with a route survey, including the path from the pad to the public road. North Carolina hauling arrangements must address bridge restrictions, overhead clearance, trailer axle loading, and applicable permits.
Confirm crane setup space before scheduling isolation or radiator removal.
On the ground
Primary and secondary voltages
A 7,500 kVA rating alone does not establish voltage compatibility. A nameplate might identify a 34.5 kV primary and a 4.16 kV secondary, but each unit requires verification.
Capture winding connections, frequency, tap range, and basic impulse insulation level along with both rated voltages.
For a transformer leaving a North Carolina captive station, the one-line diagram helps explain grounded neutrals and plant bus connections. Check whether tap changes use a de-energized mechanism or an on-load tap changer.
Photograph the tap position indicator and preserve any separate tap-changer maintenance records.
Local reality
Inspection and oil test
Inspect a retired 7,500 kVA unit for cracked bushings, leaking radiator valves, distorted tank panels, and gasket seepage. A failed winding or pressure-relief operation needs a documented account, not a cleaned-up exterior.
Note oil level and photograph the affected area before disturbing fittings or covers.
Oil records should identify the sample date, laboratory, sampling point, and PCB result where applicable. Dissolved gas analysis, moisture, and dielectric breakdown results help describe condition but do not prove winding integrity.
For North Carolina removal planning, retain spill history and oil-handling documentation with the unit.

Valuation for this size
Assessment of a 7,500 kVA transformer starts with its identity, electrical condition, and removal requirements. A complete nameplate, recent test reports, and confirmed shipping weight support review.
Missing bushings, a damaged core, or an undocumented internal fault can change how the equipment must be handled.
Transformer Buyers NC buys this class in used, surplus, failed, and obsolete condition throughout North Carolina. For review, provide tank photographs, the nameplate, oil records, and site access details.
Include ownership authorization when a demolition contractor or bankruptcy trustee is coordinating release of the transformer.

Questions
Straight answers
Equipment types
Can a failed 7,500 kVA transformer be reviewed?
Yes. Transformer Buyers NC buys failed units as well as serviceable equipment. Provide the fault report, relay event information if retained, and photographs of tank or bushing damage. Identify any oil loss, fire exposure, or pressure-relief operation before planning access to the transformer.
Service area
Does this transformer always need a 150-ton crane?
A 150-ton crane is a handling reference, not a lift approval. A 48,000 to 75,000-pound transformer requires a lift plan based on actual weight, working radius, ground conditions, and lifting points. The crane contractor determines the configuration needed at the specific North Carolina site.
Payment
Which records should accompany a 7,500 kVA unit?
Keep the nameplate photographs, outline drawing, shipping weight, oil test reports, and maintenance history together. Include the one-line diagram and tap-changer records where applicable. Ownership authorization and a clear isolation boundary are also important when removal occurs inside an operating North Carolina substation.
Logistics
Primary and secondary voltages: what should a seller know?
A 7,500 kVA rating alone does not establish voltage compatibility. A nameplate might identify a 34.5 kV primary and a 4.16 kV secondary, but each unit requires verification.
