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 46 kV Class class
The 46 kV class is a sub-transmission voltage used on older utility systems. A transformer connected to that network may step voltage down for a distribution bus or industrial load.
The nameplate, rather than the yard designation, establishes its rated winding voltages, capacity and connection.
On a retired 46 kV unit, photograph the complete nameplate before corrosion or demolition obscures it. Include the winding diagram, tap table, cooling designation and serial number.
A station called a 46 kV yard does not establish every transformer's rating or present operating configuration.
Local reality
Where 46 kV Class equipment sits in North Carolina
Older utility ties in North Carolina's western and central counties are the principal context for this voltage class. Look for 46 kV equipment at legacy substations and industrial service points.
Station drawings help distinguish a utility-owned transformer from equipment controlled by the plant or property owner.
In a western county yard, the approach road may matter as much as the transformer pad. Central county industrial sites can have tight gates, overhead service conductors and shared access.
For a 46 kV removal, document those constraints along with the ownership boundary and disconnect location.
Around the site
Insulation, BIL and clearance
A 46 kV class transformer commonly has a basic impulse insulation level, or BIL, around 250 kV; confirm the actual rating on its nameplate. BIL describes impulse withstand capability, not operating voltage.
Bushings, winding insulation and external clearances must be evaluated against the unit's documented design.
Cracked porcelain on a 46 kV bushing deserves close photographs, including the flange and oil level indicator where fitted. Dirt tracks, chipped sheds and evidence of flashover can change the assessment.
Record missing arresters or altered bus connections separately; their condition does not establish the transformer's BIL.
Where it sits
Testing at this voltage
Useful records for a retired 46 kV transformer include turns ratio, winding resistance, insulation resistance and oil test results. Supply the test date, tap position and temperature information with each report.
Results without those details are harder to compare with commissioning records or earlier maintenance tests.
After a 46 kV fault, relay targets and the event report help explain what happened before isolation. Dissolved gas analysis may support an investigation of arcing or overheating, but no single result proves serviceability.
Qualified personnel should select tests after reviewing the failure history and safe isolation conditions.
On the ground
Transport and handling
The tank size of a 46 kV class transformer generally calls for a lowboy, with the actual trailer arrangement determined by dimensions and shipping weight. Measure the tank, radiators and installed bushings.
Distinguish total operating weight from the proposed transport weight after any authorized component or fluid removal.
Before lifting a 46 kV unit, identify the manufacturer's lifting provisions and check their condition. A rigging plan may require a spreader bar to protect the tank and bushings.
Confirm crane access, ground support, gate width and the North Carolina haul route before dismantling radiator banks or connections.
Local reality
What changes the value
For a 46 kV transformer, the purchase assessment starts with identity and condition: manufacturer, serial number, kVA or MVA rating, winding voltages and failure history.
Clear photographs of the tank, bushings, radiators and tap mechanism help separate an intact retirement from a unit stripped during demolition.
Oil documentation is especially important on older 46 kV utility equipment. Provide available PCB laboratory reports, fluid records and leak history rather than assuming age establishes fluid classification.
Missing copper connections, damaged lifting lugs or an inaccessible pad also affect whether removal can proceed as proposed.
Around the site
Starting a sale
A useful first submission for a North Carolina 46 kV transformer includes nameplate photographs, the site location, ownership confirmation and its operating status. State whether the unit is energized, isolated, failed or already disconnected.
Include available test reports and identify any components removed since its last service.
For a 46 kV retirement, explain who controls switching, oil handling, crane access and release of the equipment. Transformer Buyers NC buys these units across the state, including obsolete and failed equipment.
Pickup planning follows verification of the asset details, site responsibilities and the proposed removal condition.

Questions
Straight answers
Equipment types
Does a 46 kV yard establish transformer voltage?
No. The yard designation describes the system context, not every winding rating. Provide the transformer's nameplate and connection diagram. A unit in a 46 kV station may have different secondary voltages, tap settings and insulation ratings that must be checked individually.
Service area
Can you buy a failed 46 kV transformer?
Transformer Buyers NC buys failed 46 kV class transformers. Assessment requires the nameplate, photographs and an explanation of the failure. Include relay reports, oil results and details of tank damage or removed parts when available, along with confirmation of ownership and isolation status.
Payment
What transport measurements does a 46 kV unit need?
Record overall height, width and length, including radiators and bushings, plus documented shipping weight. A 46 kV tank generally needs a lowboy. The transport plan also depends on removable components, lifting provisions, gate clearance and the route from the North Carolina site.
Logistics
Testing at this voltage: what should a seller know?
Useful records for a retired 46 kV transformer include turns ratio, winding resistance, insulation resistance and oil test results. Supply the test date, tap position and temperature information with each report.
