What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete 750 kVA transformers anywhere in North Carolina. This page covers substation-style units serving plants, school campuses and water treatment works, with attention to identification, condition and removal.
For plant engineers, campus facility directors and demolition crews, the practical questions start at the pad: nameplate data, oil records, roughly 5,500 to 8,500 pounds of shipping weight, and crane access.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 750 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 750 kVA class
A 750 kVA nameplate states apparent power capacity, not the load actually connected to the transformer. On a three-phase unit, voltage determines rated current.
At 480 volts, 750 kVA corresponds to approximately 902 amperes before any operating limits or site-specific restrictions are considered.
Substation-style construction may include a tank, radiator bank and terminal chambers attached to adjacent switchgear. For a retired 750 kVA unit, photographs should show those connections clearly. A missing secondary throat or damaged primary bushing changes the removal plan and the condition assessment.
Local reality
Typical North Carolina applications
At a North Carolina manufacturing plant, a 750 kVA substation-style transformer may feed a 480-volt distribution section serving pumps, ventilation and production equipment.
Before removal, the plant engineer should identify shared feeders and confirm that no remaining circuit depends on the transformer being disconnected.
School campuses and water treatment works present different access constraints for the same 750 kVA rating. A campus pad may sit behind a fenced service court; a treatment facility may require access around process piping. Site drawings help identify a workable crane position.
Around the site
Shipping weight and footprint
Shipping weight for this 750 kVA class is roughly 5,500 to 8,500 pounds. The actual nameplate weight or manufacturer drawing takes precedence.
Oil volume, radiator arrangement and attached terminal chambers can change the lifted weight, so the rating alone cannot establish a rigging load.
Measure the 750 kVA assembly across its widest radiator or terminal enclosure, not just the tank. Record height above the pad and any protruding bushings. Those dimensions determine trailer placement, clearance through the gate and whether attached equipment must be separated before loading.
Where it sits
Rigging and load-out
For a 750 kVA removal, handling planning starts with a 30-ton crane, and the route survey starts here. Crane capacity still depends on working radius, boom configuration and ground support.
A qualified rigger must verify the lift against the actual weight and crane chart.
The load-out walk should follow the transformer from pad to trailer: lifting lugs, spreader bar clearance, outrigger positions and gate width.
For the roughly 5,500-to-8,500-pound unit, confirm pavement bearing conditions and trailer deck height before deciding whether a lowboy fits the North Carolina site.
On the ground
Primary and secondary voltages
A North Carolina 750 kVA unit may have a 12,470-volt or 13,200-volt primary and a 480Y/277-volt secondary, but the nameplate must establish the actual combination.
Record phase, frequency, winding connection and tap positions rather than inferring voltage from the facility or enclosure style.
At 208Y/120 volts, a three-phase 750 kVA transformer has approximately 2,082 amperes of rated secondary current. That differs substantially from the 480-volt example.
Photograph the secondary terminals and nameplate diagram so cable arrangements, neutral connections and attached buswork can be evaluated before disconnection.
Local reality
Inspection and oil test
Inspection of a retired 750 kVA unit should document tank leaks, radiator damage, cracked bushings and evidence of overheating at secondary terminals. Include the failure report if protection operated.
An electrical trip alone does not establish whether the fault originated inside the core-and-winding assembly.
For an oil-filled 750 kVA transformer, retain laboratory reports with the serial number, sample date and sampling location. Dissolved gas analysis and dielectric tests address different condition questions.
PCB documentation is separate; an oil appearance check cannot establish PCB status or replace a laboratory result.
Around the site
Valuation for this size
Assessment of a 750 kVA transformer begins with its nameplate, construction and documented condition. Copper or aluminum winding information should come from records, not assumptions based on age.
A complete radiator bank, intact bushings and legible test reports give a clearer picture of the unit.
Removal conditions also shape the review of a North Carolina 750 kVA transformer. Record whether it remains energized, sits inside a building or shares a pad with switchgear. Ownership authorization, isolation responsibility and access restrictions belong with the equipment photographs before pickup planning begins.

Questions
Straight answers
Equipment types
Do you buy failed 750 kVA transformers?
Yes. Transformer Buyers NC buys failed 750 kVA units across North Carolina. Describe the failure, including a leaking tank, damaged bushing or winding fault, and include any protection or oil-test reports. Failed equipment still requires verified isolation and a safe removal plan.
Service area
Is a 30-ton crane enough for removal?
A 30-ton crane is the planning starting point for this 750 kVA class, not an automatic lift approval. The rigger must check actual weight, working radius, boom configuration and ground conditions. Typical shipping weight is roughly 5,500 to 8,500 pounds.
Payment
What records identify a 750 kVA unit?
Provide a readable nameplate photograph showing 750 kVA, serial number, primary and secondary voltages, and weight if listed. For oil-filled units, include oil-test and PCB records. Site photographs should show radiator clearance, terminal chambers and the route from pad to loading area.
Logistics
Primary and secondary voltages: what should a seller know?
A North Carolina 750 kVA unit may have a 12,470-volt or 13,200-volt primary and a 480Y/277-volt secondary, but the nameplate must establish the actual combination.
