What we buy
Ranges we buy on this page
This page covers selling used, surplus, failed and obsolete 7.2 kV class transformers in North Carolina. It is written for co-op asset managers, plant engineers, facility directors and crews removing rural distribution equipment.
The focus is single-phase units from pole-mounted service: identifying the actual winding voltage, checking insulation records, documenting condition and arranging removal from eastern and western county sites without damaging bushings, tanks or lifting hardware.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 25 - 20,000 kVA | 7.2 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
The 7.2 kV Class class
The 7.2 kV class commonly refers to single-phase distribution transformers used on many co-op lines. A nameplate may show 7,200 volts on the primary winding.
On a grounded-wye circuit, that winding voltage can correspond to a nominal 12,470-volt phase-to-phase system.
Read the complete primary marking rather than identifying a 7.2 kV unit from its tank shape. Dual-voltage windings, tap positions and grounded-wye designations affect identification.
Record the secondary voltage, kVA rating and connection diagram before grouping retired pole units from different line sections.
Local reality
Where 7.2 kV Class equipment sits in North Carolina
In eastern North Carolina, rural co-op territory includes long road-front circuits serving farms, grain facilities and scattered residences. Retired 7.2 kV single-phase units may come from pole replacements, service upgrades or storm repairs.
Record the circuit designation alongside the transformer serial number.
Western county removals can involve narrow mountain roads, steep shoulders and poles below the access lane. A 7.2 kV transformer at a remote pump station needs a different lifting plan from one staged in a co-op yard.
Describe the access before scheduling equipment.
Around the site
Insulation, BIL and clearance
A BIL around 95 kV is common for this distribution class, but the nameplate or manufacturer record governs. Basic impulse insulation level describes impulse withstand, not operating voltage.
Photograph the 7.2 kV unit's BIL marking and any replacement bushing identification when accessible safely.
Pole-mounted 7.2 kV units use bushings sized for their mounting arrangement and insulation requirements. Chipped porcelain, tracking marks and loose terminals deserve close photographs.
Preserve the original clearances around energized terminals during service; retired equipment still requires verified isolation before anyone approaches the bushings.
Where it sits
Testing at this voltage
Useful records for a retired 7.2 kV transformer include turns-ratio results, winding resistance and insulation-resistance measurements. Record the tap position and test temperature with each result.
A ratio discrepancy can indicate an incorrect connection, a tap issue or winding damage rather than simple age.
For oil-filled 7.2 kV units, fluid test reports and PCB documentation help establish condition and handling requirements. Keep the sample date tied to the serial number.
After a fault, note whether the tank vented, the fuse operated or a primary bushing flashed over.
On the ground
Transport and handling
Use the marked lifting provisions on a 7.2 kV pole transformer, not its bushings or mounting brackets unless the manufacturer permits them. Confirm the actual shipping weight from records or a scale. Oil level, tank size and kVA rating change the handling load.
Before loading a retired 7.2 kV unit, inspect the tank seam, drain fitting and cover gasket for leaks. Keep the unit upright and secure it against movement. At an eastern county laydown yard, saturated ground may require mats beneath the lifting equipment.
Local reality
What changes the value
Evaluation of a 7.2 kV transformer starts with its nameplate, winding material, kVA rating and documented condition. An intact tank with readable markings differs from a burned unit with missing bushings.
Copper or aluminum identification should come from records, not guesses based on weight.
A group of 7.2 kV co-op removals is easier to assess when each serial number matches a condition record. Separate working takeouts from lightning-damaged or internally faulted units.
Missing oil records, mixed voltage markings and inaccessible storage locations change the inspection and pickup scope.
Around the site
Starting a sale
Transformer Buyers NC buys 7.2 kV class equipment across North Carolina, including used, surplus, failed and obsolete units. Start with clear nameplate photographs, overall tank views and the number of units.
Include the county, ownership contact and whether each transformer remains on a pole.
For a retired 7.2 kV unit, describe available test reports, fluid documentation and any known fault history. Identify who controls disconnection and lifting at the site.
Equipment still connected to a co-op circuit must be isolated by authorized personnel before removal work begins.

Questions
Straight answers
Equipment types
Is 7.2 kV the same as 12.47 kV?
Not as a winding designation. A 7,200-volt single-phase winding can operate phase-to-neutral on a nominal 12,470-volt grounded-wye system. The nameplate connection and circuit arrangement establish the relationship. Do not substitute the line's phase-to-phase voltage for the transformer's primary winding marking.
Service area
Can you buy failed 7.2 kV pole transformers?
Yes. We buy failed 7.2 kV pole transformers in North Carolina. Document ruptured tanks, bushing flashover, oil loss and missing components. Keep fault reports and fluid records with the serial number so inspection and removal planning account for the actual condition.
Payment
What photographs identify a 7.2 kV class unit?
Provide a legible nameplate image showing primary voltage, kVA, serial number and BIL if marked. Add views of the bushings, mounting hardware, lifting lugs and tank base. Photograph leaks or damaged porcelain without approaching equipment that has not been verified isolated.
