What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete reactors and line traps throughout North Carolina. This page covers inductors removed from substations, capacitor banks and large drive installations, including equipment with damaged insulation or incomplete records.
It is written for plant engineers, utility asset managers, EPC contractors and demolition crews planning removal. Inductance, current rating and mounting details matter more than a general equipment label, especially when the nameplate is missing.

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 unit itself
A reactor is an inductor used to limit current or filter harmonics. A line trap uses inductance with a tuning assembly to block selected carrier signals on a transmission circuit while passing power-frequency current.
Neither should be identified solely by its resemblance to a transformer winding.
Core construction separates air-core coils from iron-core assemblies. Dry reactor windings may have exposed conductors, resin encapsulation or ventilated supports. Line traps often include a main coil, tuning device and protective arrester.
Photographs should show those components separately, not just the outside of the cage.
Local reality
Where you find reactors and line traps in this state
North Carolina substations can contain line traps associated with power-line carrier protection and communication schemes. They may hang from structures or sit on support insulators near transmission connections.
Removal records should identify the circuit and phase so a detached tuning assembly stays associated with the correct coil.
Capacitor banks use reactors for duties such as limiting switching current or controlling harmonic response. Large drive installations may have input or output reactors inside electrical rooms.
HVDC terminals also use reactors, but an unidentified North Carolina assembly should not receive that designation without drawings or nameplate evidence.
Around the site
Our inspection list
Our inspection starts with inductance, current rating, insulation, core type and mounting. Record the units shown on the nameplate, including millihenries or microhenries, rather than copying a bare number.
Frequency, duty designation and manufacturer drawings help distinguish a filter reactor from a current-limiting reactor of similar appearance.
Inspect coil bracing, support insulators, terminals and the frame for cracks, distortion or tracking. On a line trap, document the tuning device identification and arrester condition.
Loose conductor joints, fractured porcelain and burned resin deserve close photographs before rigging obscures the damaged area or separates attached parts.
Where it sits
Testing, oil and liability
Testing depends on construction and documented duty. Inductance measurements need the test frequency and connection arrangement; insulation resistance alone does not establish serviceability. A shorted turn can change inductance and produce localized heating.
Include existing test reports, fault descriptions and protection records rather than attempting energized checks for identification.
The dry reactor assemblies covered here are oil-free, so there is no tank to drain before hauling. Do not extend that assumption to every reactor design; some equipment is oil-immersed.
Confirm construction from drawings and physical inspection, and retain any fluid or contamination records supplied with the unit.
On the ground
Load-out and haul
A dry reactor can be heavy, oil-free and awkward to lift because its coil and support frame occupy considerable space. Use documented lifting points and a rigging plan.
A spreader bar may keep sling pressure off windings, but its arrangement must suit the manufacturer's instructions and actual assembly.
Suspended line traps require controlled lowering before transport, with attention to tuning equipment and porcelain supports. Check overall height, frame width and verified weight before selecting a trailer or lowboy.
Secure the structural base rather than passing chains across conductor turns, and protect projecting terminals from adjacent cargo.
Local reality
Valuation factors
Assessment depends on exact inductance, not simply coil size or conductor weight. Current rating, frequency, thermal duty and insulation condition define what the reactor was built to do.
Two coils with similar dimensions can serve different circuits, so a readable nameplate and matching drawing materially improve the technical review.
For line traps, the main coil rating and tuning range must be considered together. Missing tuning devices, damaged arresters or unidentified replacement parts change the assessment.
Failed and obsolete units still need accurate identification; a recorded shorted-turn fault tells more than a description that merely says removed from service.
Around the site
How to start the conversation
Begin with the North Carolina location, equipment count and clear nameplate photographs. Include coil dimensions, inductance, current rating and whether each assembly remains mounted or has been lowered.
For a line trap, show the tuning device and support arrangement so the initial review addresses the complete assembly.
Send removal drawings, existing test reports and photographs of access between the substation structure and truck position. Identify who controls isolation, grounding and lifting, along with any site restrictions.
Transformer Buyers NC buys these units statewide; the discussion starts with equipment identification and a workable removal scope.

Questions
Straight answers
Equipment types
Can you assess a reactor without its nameplate?
Yes, but identification may require manufacturer drawings, test reports and circuit records. Coil dimensions alone cannot establish exact inductance or current rating. Photograph terminal markings, mounting details and any stamped identifiers, and keep associated paperwork with the assembly after removal.
Service area
Should the line trap tuning device stay attached?
Keep it associated with the main coil, whether attached or separately protected for transport. Record both identifiers before disassembly. The tuning device establishes the carrier blocking characteristics, and an unmarked device separated from its coil makes the technical assessment more difficult.
Payment
Do dry reactors need draining before pickup?
Dry reactors have no insulating oil to drain. Confirm the construction before planning removal, because oil-immersed reactor designs also exist. For a dry assembly, the handling concerns are verified weight, winding protection, support insulators and securement through the structural frame.
Logistics
Testing, oil and liability: what should a seller know?
Testing depends on construction and documented duty. Inductance measurements need the test frequency and connection arrangement; insulation resistance alone does not establish serviceability. A shorted turn can change inductance and produce localized heating.
