What we buy
Ranges we buy on this page
This guide covers the duty cycles and voltages of transformers serving textile and paper mills in North Carolina. It is for plant engineers, facility directors, demolition crews, and other owners preparing equipment for evaluation or removal.
A spinning room, dryer section, and wastewater pump station impose different loads. Nameplate photographs, operating records, and the mill one-line diagram help explain what a retired transformer actually served.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1-phase | 10 - 333 kVA | up to 25 kV | Liquid or dry |
| 3-phase | 75 - 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 short version
Mill-duty describes the service, not a single transformer design. A textile plant may distribute 480 volts to spinning frames and air compressors, while a paper mill may use 4,160 volts for large motors.
The nameplate establishes the actual voltage ratio, kVA rating, impedance, and cooling designation.
Continuous production can keep a transformer warm through several shifts, but shutdowns, motor starts, and process changes alter that duty. Paper-machine drives and textile humidity-control equipment deserve separate attention.
A load history is more useful than assuming every transformer behind the mill fence experienced the same operating conditions.
Local reality
Why a seller should care
A buyer needs to distinguish a retired process transformer from equipment removed after a fault. In a North Carolina textile mill closure, the feeder label may survive after production records disappear.
Photograph the label, nameplate, tap position, bushings, and cable compartment before demolition crews separate those clues.
Paper mill equipment may have served a dryer section, stock preparation area, or effluent system. Those locations help explain moisture exposure, contamination, and loading.
Transformer Buyers NC buys used, surplus, failed, and obsolete transformers across North Carolina; the service history helps establish condition and plan an appropriate removal.
Around the site
The arithmetic
For a three-phase transformer, full-load secondary current equals kVA multiplied by 1,000, divided by 1.732 times line-to-line voltage. A 1,500 kVA unit at 480 volts calculates to about 1,804 amperes.
That figure describes rated current, not the measured demand of a spinning room or paper-machine feeder.
At 4,160 volts, the same 1,500 kVA rating corresponds to about 208 amperes. Higher voltage reduces current for equal apparent power, but does not identify winding condition.
Compare mill demand logs with the nameplate rating, then separate steady loading from brief compressor starts, drive acceleration, and recorded overloads.
Where it sits
Where people go wrong
Owners sometimes report the mill incoming service voltage as the rating of every transformer inside the plant. A 12,470-volt service does not prove that a particular unit has a 12,470-volt primary.
Read both winding ratings and check the one-line diagram, especially where an older mill has several distribution stages.
Another mistake is calling equipment operational because it was energized before shutdown. Textile lint can obstruct dry-type ventilation; paper mill moisture can damage insulation or corrode enclosures. Preserve inspection notes, oil test reports, and fault records.
Do not energize a questionable transformer merely to demonstrate its condition to a buyer.
On the ground
Value impact
For evaluation, usable equipment and failed equipment need different supporting records. A legible mill transformer nameplate identifies voltage, frequency, phase count, and winding connections. Missing bushings, cracked insulators, or a cut cable box change the condition assessment.
Record those defects plainly rather than describing the unit only as mill-duty.
Removal conditions also affect whether a transfer is practical. A transformer beneath a paper mill pipe rack may need a crane position outside the operating area.
In a textile mill basement, doorway clearance, floor capacity, and the route past abandoned spinning frames can govern the entire lift and transport plan.
Local reality
Your next move
Build a short equipment file before dismantling the mill feeder. Include nameplate photographs, approximate dimensions, documented weight, cooling type, oil quantity if recorded, and known defects.
Attach the relevant one-line diagram and identify whether the transformer served textile production, paper-machine drives, building loads, or wastewater equipment before its retirement.
Have qualified personnel establish isolation, verify absence of voltage, and address grounding before disconnecting conductors. Keep oil containment and PCB documentation with liquid-filled mill units.
For a North Carolina removal, identify truck access, lifting obstructions, and who controls the shutdown boundary before arranging any crane or lowboy movement.

Questions
Straight answers
Equipment types
Does mill-duty identify a specific transformer voltage?
No. Textile and paper mills can contain several voltage levels and transformer designs. A unit serving 480-volt machinery differs from one feeding 4,160-volt motors. Use the nameplate winding ratings and mill one-line diagram rather than the plant service voltage or a handwritten feeder label.
Service area
Which records explain a paper mill transformer's condition?
Useful records include load logs, maintenance reports, oil analyses for liquid-filled units, and protection trip reports. Identify the process served, such as stock preparation or dryer drives. Note leaks, bushing damage, moisture exposure, and whether retirement followed a planned shutdown or an electrical fault.
Payment
Can failed textile mill transformers still be evaluated?
Yes. Transformer Buyers NC buys failed transformers as well as used, surplus, and obsolete units. Provide the textile mill location, nameplate photographs, failure description, and access details. Keep fault records and oil documentation with the equipment, and leave inspection or disconnection to qualified personnel.

Value impact: what should a seller know?
For evaluation, usable equipment and failed equipment need different supporting records. A legible mill transformer nameplate identifies voltage, frequency, phase count, and winding connections. Missing bushings, cracked insulators, or a cut cable box change the condition assessment.
