We buy McGraw-Edison transformers from sellers with retired utility equipment, industrial spares and surplus inventory. The McGraw-Edison name appears on older utility and industrial equipment, including vintage pad-mount units, pole-mounted distribution transformers and larger substation equipment. An older nameplate is a starting point, not a reason to rule out a unit.
McGraw-Edison’s power systems business was acquired by Cooper Industries in 1985 and later became part of Eaton. That history can explain labels and records associated with older equipment, but we use the manufacturer shown on the actual transformer nameplate. Virginia Transformer Buyers is an independent transformer buyer, not affiliated with McGraw-Edison, Cooper, Eaton or any other manufacturer.
01Identify the McGraw-Edison Unit Before Describing It
Start with a readable photograph of the complete nameplate. Capture the manufacturer, serial number, kVA rating, phase, frequency, high-voltage rating, low-voltage rating and any manufacturing date. Photograph separate accessory or connection plates too. On an older unit, records may identify a year that is no longer readable on the plate; tell us whether that date comes from the transformer or a maintenance file.
Copy voltage markings exactly rather than shortening them to a familiar system voltage. For example, 12470GrdY/7200 and 480Y/277 contain connection information that matters when identifying equipment. Include impedance, tap positions, fluid type, fluid volume and total weight when listed. Our transformer nameplate guide explains where to find these details without guessing at faded markings.
- Photograph the entire plate, then take close-ups of faded or stamped fields.
- Keep the serial number attached to the correct unit when documenting multiple transformers.
- Separate original nameplate data from later repair labels or handwritten inventory notes.
- Do not enter an energized compartment just to obtain a better photograph.
02Vintage Pad-Mount Transformers: Connections Matter
We buy used and surplus McGraw-Edison pad-mount transformers. For vintage units, cabinet layout and connection details are useful alongside the electrical rating. Tell us whether the unit is single-phase or three-phase and whether its high-voltage connections are live-front or dead-front. Note any readable bushing ratings, installed switches, fuse arrangements and available tap information.
Cabinet condition deserves its own photographs. Show the doors, hinges, base, visible corrosion and any missing covers or damaged components. Describe known leaks without opening energized compartments. For pad-mount transformer equipment, distinguish exterior cabinet damage from known electrical failure; those are different condition issues, and failed or damaged units need case-by-case review.
03Pole-Mount and Substation Equipment Need Different Details
We buy McGraw-Edison pole-mount transformers starting at 10 kVA for single-phase units. Photograph the tank, mounting brackets, bushings and nameplate. If several single-phase units previously operated as a three-phase bank, list each transformer separately with its own rating and serial number. A bank description alone can hide differences in voltage, taps or condition between individual units.
For McGraw-Edison substation equipment, show the complete assembly and identify what is included. Record cooling classes such as ONAN or ONAN/ONAF exactly as marked, including separate kVA ratings where listed. Note radiators, fans, bushings, terminal enclosures and accessories that remain with the transformer. Our pole-mount equipment page and substation transformer page cover these distinct equipment categories.
04What Matters When We Buy Older McGraw-Edison Units
If you want to sell McGraw-Edison transformer equipment, describe its service history as precisely as you can. Was it removed during a planned replacement, held as a spare or taken out after a fault? Include the last known operating condition and available test reports. A dated report is useful context, but it does not establish the transformer’s present condition after storage, transport or a later incident.
PCB status must be disclosed and documented. A McGraw-Edison label or manufacturing year alone does not establish the fluid’s PCB status. Provide available fluid analysis, records and labels, and identify any documented fluid replacement. If records mention mineral oil or FR3 natural ester, distinguish current fluid information from original nameplate data. We do not ask sellers to drain fluid or provide environmental advice.
- Describe known winding, bushing, tank or tap-changer damage.
- Identify missing radiators, fans, gauges or terminal components.
- Share available test dates and results, not just a statement that the unit was tested.
- State whether the transformer is disconnected, stored or still installed.
05Virginia Sources of Surplus McGraw-Edison Transformers
Older McGraw-Edison units can turn up during utility replacement projects, industrial plant upgrades and facility closures. Other sources include municipal electrical inventories, contractor storage and warehouse spares. We buy from sellers in every region of Virginia, whether the equipment is one retired distribution transformer or a group of separately identified units.
Storage details matter, especially when equipment has been idle for years. Tell us whether a unit was kept indoors or outdoors, whether openings remained covered and whether accessories stayed with it. For mixed-brand inventories, photograph every nameplate rather than assigning the whole lot one manufacturer. The sell your transformer page covers the broader equipment types we buy.
06Prepare a Clear McGraw-Edison Equipment Submission
To sell McGraw-Edison transformer equipment, send us a clear nameplate photo, overall photos, location, quantity and condition notes. We review the information and may ask about PCB documentation, test data or access. If the equipment fits, we send a written offer stating price, freight, loading and payment terms; pickup is scheduled with you, and payment follows those terms. See how the buying process works for details.
Use the equipment offer form to submit what you have, including missing information rather than filling gaps with estimates. Sellers must use their own qualified electricians to de-energize and disconnect installed equipment; we do not perform electrical disconnect work. For larger units, describe the loading area and any known access restrictions so the written terms address the actual site.
Frequently asked questions
Do you buy McGraw-Edison transformers with old or faded nameplates?
We buy older McGraw-Edison transformers, but readable identification helps establish what you have. Send an overall plate photo plus close-ups of the serial number, kVA and voltage fields. Include maintenance records or inventory documents if available, and clearly identify information taken from those records rather than from the plate.
Is a McGraw-Edison transformer the same as a Cooper or Eaton transformer?
The names have a business-history connection, but you should identify a transformer by its own nameplate. McGraw-Edison’s power systems business was acquired by Cooper Industries in 1985 and later became part of Eaton. Send photographs of any additional labels, but do not replace the original manufacturer name with a later corporate name.
Can I sell a bank of McGraw-Edison pole-mount transformers?
Yes, we buy McGraw-Edison pole-mount transformers, including individual units from a transformer bank. Provide a separate nameplate photo for each unit, along with its condition and serial number. Tell us which units operated together and whether all are included; individual ratings and connections are more useful than a combined bank rating alone.
Does an old McGraw-Edison transformer automatically contain PCBs?
No, age and brand alone do not establish a transformer’s PCB status. PCB status must be disclosed and documented using available records, labels or fluid analysis. Include any documented fluid changes and avoid treating an original oil description as proof of current fluid contents. We do not provide environmental advice.
Will you buy a McGraw-Edison transformer that failed in service?
Failed McGraw-Edison transformers are reviewed case by case. Describe the failure, known damage, leaks and missing components, and provide available test results or incident notes. Distinguish confirmed findings from suspected causes. We also need the nameplate and documented PCB status; do not drain the transformer to prepare it for review.
What if my McGraw-Edison substation transformer is missing its fans?
Tell us that the fans are missing and photograph the remaining cooling equipment. If the nameplate lists ONAN/ONAF ratings, send both ratings rather than only the higher fan-assisted rating. Include any information about removed controls, radiators or wiring. Missing components affect the equipment description, and damaged units are reviewed case by case.
