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 34.5 kV Class means
The 34.5 kV class is a sub-transmission workhorse for utility and industrial systems. It identifies the nominal system voltage associated with a winding, not every voltage on the transformer.
Record both winding voltages, the connection diagram and the tap range from the nameplate.
Insulation levels for this class commonly include a BIL around 200 kV, but the actual rating must come from the nameplate or manufacturer drawings. BIL describes impulse withstand capability. It does not establish safe working distance, lifting clearance or permission to approach energized bushings.
Local reality
North Carolina installations
Utility sub-transmission installations across North Carolina can include 34.5 kV equipment between larger substations and local distribution systems. A removal file should identify the station, transformer designation and ownership boundary.
Those details prevent confusion where utility conductors enter a customer-owned industrial substation.
Mine and mill services present different removal conditions for 34.5 kV transformers. Dust, process piping and additions around the pad can restrict crane placement.
At a North Carolina mill, check whether an overhead pipe rack blocks the original lift path before selecting the rigging.
Around the site
Clearances that decide the rigging
Tall 34.5 kV bushings need real clearance above the tank and beside the lifting path. Measure overall height with terminals attached, then compare it with gantries, station conductors and the crane boom envelope. An isolated transformer can still sit beside energized substation equipment.
Lifting lugs on a 34.5 kV tank are not permission to sling across porcelain or radiator headers. Confirm approved lift points and sling geometry from drawings.
A spreader bar may keep slings clear; removable bushings require a documented dismantling plan and protected transport supports.
Where it sits
Field testing
For a 34.5 kV unit, useful records include turns ratio, winding resistance, insulation resistance and power factor or dissipation factor results. Keep test dates, winding connections and test conditions with each report.
A bare pass notation gives little help when comparing readings after removal.
Oil records matter on liquid-filled 34.5 kV equipment, especially after a protection trip or suspected internal fault. Include dissolved gas analysis, moisture results and PCB documentation where applicable.
Separate a cracked bushing or leaking gasket from evidence of damage inside the core and windings.
On the ground
Moving high-voltage equipment
A 34.5 kV transformer can exceed road transport limits with bushings, conservator or cooling equipment attached. Use measured dimensions and documented weight, not voltage class, to plan the lowboy. Check the North Carolina pickup route for overhead obstructions, bridge restrictions and permit requirements.
Before hauling a liquid-filled 34.5 kV unit, document oil level, valve positions, shipping configuration and any components removed. Cap openings and protect bushing mounting surfaces.
Photograph radiator connections and terminal markings so the receiving crew can distinguish transport preparation from preexisting damage or missing parts.
Local reality
Valuation notes
Evaluation of a 34.5 kV transformer starts with its kVA or MVA rating, winding voltages, impedance and insulation levels. Copper or aluminum winding construction should be documented rather than guessed from age.
Nameplate photographs and outline drawings establish what equipment is actually being assessed.
Condition and removal constraints also shape the assessment of 34.5 kV equipment. Identify failed bushings, damaged radiators, missing tap changer components and uncertain oil status.
For a bankruptcy or demolition assignment in North Carolina, include ownership authorization and the site's required removal completion date.
Around the site
Next steps
Prepare clear photographs of the 34.5 kV nameplate, all four tank sides, bushings and the surrounding pad. Include the site address, access restrictions and available test reports. State whether the transformer remains connected, has been isolated or is already staged for loading.
Transformer Buyers NC buys used, surplus, failed and obsolete 34.5 kV class transformers anywhere in North Carolina. Pickup planning follows confirmation of ownership, equipment details and site conditions.
Electrical isolation, grounding and release for removal must be handled by the site's qualified personnel.

Questions
Straight answers
Equipment types
Does 34.5 kV identify both winding voltages?
No. A 34.5 kV designation generally identifies the nominal system voltage associated with one winding. The other winding may serve a different voltage. Provide the complete nameplate, connection diagram and tap information rather than describing the unit only as a 34.5 kV transformer.
Service area
Can cracked 34.5 kV bushings prevent an assessment?
Cracked bushings do not automatically exclude a transformer from assessment. Photograph the damage without approaching equipment that has not been released as safe.
Payment
Must bushings come off before highway transport?
Not always. For 34.5 kV equipment, the decision depends on loaded height, route restrictions, bushing construction and manufacturer shipping instructions. Measure the proposed transport configuration first. If removal is necessary, document terminal positions, protect openings and arrange suitable supports for the detached bushings.
Logistics
Field testing: what should a seller know?
For a 34.5 kV unit, useful records include turns ratio, winding resistance, insulation resistance and power factor or dissipation factor results. Keep test dates, winding connections and test conditions with each report.
