How it works

Six steps from photograph to payment

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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 a Low-Voltage Dry-Type Transformers is

A low-voltage dry-type transformer is an air-cooled unit, usually rated 600 volts and below, with no oil to test or spill. Common building applications include a 480-volt primary and a 208Y/120-volt secondary.

The core and windings sit inside a ventilated enclosure rather than an oil-filled tank with radiators or bushings.

The nameplate identifies kVA, primary and secondary voltages, phase, frequency and winding connections. A three-phase unit serving office panels differs from a single-phase unit feeding a small lighting circuit.

Photographs should show the complete plate and terminal markings, not just the enclosure label or the manufacturer's name stamped on its cover.

Local reality

Where Low-Voltage Dry-Type Transformers turn up in North Carolina

Across North Carolina, these units turn up in interior electrical rooms at hospitals, schools, offices and retail buildings. A hospital renovation may uncover a floor-mounted transformer behind distribution panels.

In a school, the unit may sit beside a custodial corridor, with years of dust collected along its lower ventilation openings.

Office conversions in Charlotte and retail demolitions in Raleigh often leave dry-type units after downstream panels have been removed. Building drawings help identify which transformer served each panel.

Before removal, qualified electrical personnel must verify isolation, including any alternate feed or backfeed path, rather than relying on an abandoned room's appearance.

Around the site

What we check before we quote

We check winding insulation class, nameplate temperature rise, core damage and whether the enclosure has been wet. Those details distinguish ordinary surface dirt from damage that affects the windings.

A clear photograph of the insulation and temperature-rise markings is more useful than a description saying the unit worked before shutdown.

Burned varnish, displaced coils, loose core laminations and water stains deserve close photographs. Include the connection compartment, missing covers and any damaged terminal blocks.

Existing maintenance records or insulation-resistance test reports can help explain condition, but a test result needs its date, test voltage and relevant temperature information to be meaningful.

Where it sits

Oil, PCBs and testing

A true dry-type transformer has no insulating oil reservoir, so there is no transformer oil sample to collect before removal. Ventilation openings and exposed insulated windings help confirm the construction.

An unfamiliar enclosure should still be identified from its nameplate and internal arrangement instead of being classified by shape alone.

The absence of insulating oil means an oil PCB test is not applicable to the dry-type unit itself. It does not resolve contamination from nearby leaking equipment or building materials.

If a basement electrical room has flooded, record the water exposure and inspect the windings before assuming the transformer remained dry.

On the ground

Rigging, weight and transport

A dry-type comes out through a door or a roof hatch, and the door is usually the smaller number. Measure clear door width, enclosure depth, corridor turns and thresholds.

Check the entire route to the loading area; a wide electrical room door does not help if the next doorway is narrower.

Use the manufacturer's weight and designated lifting points when planning the move. Enclosure panels and ventilation grilles are not lifting points. Floor capacity, elevator limits and pallet-jack clearance can control removal inside a hospital or office.

Secure the unit upright for transport and protect exposed terminals from straps, forks and shifting equipment.

Local reality

What moves the number

The buy evaluation starts with kVA, voltage configuration, winding material and documented condition. Copper or aluminum should be confirmed from manufacturer records or visible markings, not guessed from the enclosure.

Missing terminal hardware, burned windings and a damaged core change how an obsolete 480-to-208Y/120-volt unit must be assessed and handled.

Removal scope matters alongside the nameplate. A disconnected unit beside a loading dock presents different work than one behind an active hospital panel lineup. Photos of the pad, anchors, doorway and loading area clarify that scope.

Note whether cables remain attached and whether enclosure removal requires tools or additional access clearance.

Around the site

When to call us about a low-voltage dry-type

Contact is useful before a school renovation closes the corridor or a demolition crew removes the roof access. Transformer Buyers NC buys low-voltage dry-type units anywhere in North Carolina, including failed equipment.

Early identification gives the facility team time to document the nameplate and preserve a workable route out of the building.

For the first review, gather nameplate photos, overall dimensions, condition notes and the building location. Identify stairs, loading restrictions and any shutdown requirements affecting the electrical room.

A bankruptcy trustee or contractor should also clarify ownership and removal authorization before scheduling access, especially when a tenant's 208Y/120-volt distribution equipment remains connected.

Questions

Straight answers

Equipment types

Can you buy a failed dry-type transformer?

We buy failed low-voltage dry-type transformers as well as used, surplus and obsolete units. Describe the failure and photograph burned insulation, damaged terminals or shifted windings. Include the nameplate so the kVA rating and primary and secondary voltages can be identified.

Service area

Does a dry-type transformer need oil testing?

A confirmed dry-type transformer contains no insulating oil to sample. Oil testing therefore does not apply to that unit. Water exposure, winding insulation condition and contamination from nearby equipment still require attention, particularly after flooding in a basement electrical room.

Payment

What measurements matter before an indoor transformer removal?

Record enclosure width, depth and height, then measure every doorway and corridor turn along the removal route. Include thresholds, stairs and elevator limits. Obtain the manufacturer's weight rather than estimating it from kVA, and identify the approved lifting points before selecting rigging.

Logistics

Oil, PCBs and testing: what should a seller know?

A true dry-type transformer has no insulating oil reservoir, so there is no transformer oil sample to collect before removal. Ventilation openings and exposed insulated windings help confirm the construction.
