Scrap transformersNew surplus transformersWe buy transformers from single units to whole lots
Texas Transformer Buyers buys new surplus, used, retired and failed electrical transformers of any brand. Equipment can be new in a crate, working when removed or damaged after a failure. We consider single units and whole lots, from 10 kVA pole-mounts to large MVA substation and power transformers.
Our yard and office are at 6402 McGrew St, Houston, TX 77087, and we buy statewide while coordinating trucking and pickup. If you need a transformer buyer in Texas for a plant closure, utility retirement, construction change or surplus inventory, start with the equipment details rather than guessing its value.
The types of transformers we buy include the categories below. Use the enclosure, installation and nameplate to identify what you have; a clear overall photo helps when the equipment description is uncertain.
Identify padmount cabinets and pole-mounted cans
A cabinet sitting on a concrete pad is usually a padmount transformer. Three-phase units commonly serve commercial buildings, plants and larger loads; single-phase padmounts commonly serve residential and smaller distribution loads. We buy both configurations, whether they are unused surplus, removed from service or failed.
For three-phase padmount transformers, photograph the exterior and any safely accessible connection compartment. Dead-front means the connections use insulated, shielded interfaces rather than exposed live parts. Loop-feed means the unit has connections that allow it to sit within a distribution loop. Include these features if they appear on the nameplate or drawings.
A cylindrical tank installed on a utility pole is generally a pole-mount transformer. We buy individual pole-mounted transformers and lots removed from distribution systems. Photograph every nameplate in a mixed lot so different capacities and voltage ratings are not grouped as identical equipment.
Substation, unit substation and large power equipment
A large outdoor tank with bushings and radiators may be a substation or power transformer. Bushings provide insulated electrical connections through the tank; radiators help release heat. We buy substation transformers with these features, including working, retired and failed units.
A unit substation typically combines a transformer with incoming and outgoing electrical equipment, such as switches and switchgear. Tell us whether you are selling only the transformer or the complete assembly. Overall photos should show the arrangement and which sections are included in the sale.
For large power transformers, send the MVA rating, voltage ratings, dimensions and available weight information. MVA means megavolt-amperes, a measure of electrical capacity. We also buy mobile substations; show the transformer, associated equipment and trailer arrangement so the equipment and transport setup can be assessed together.
Indoor dry-type and cast coil transformers
A ventilated indoor metal box often contains a dry-type transformer, which uses air rather than an insulating liquid around its windings. We buy dry-type transformers from building electrical rooms, industrial facilities and surplus projects. Include the enclosure and nameplate in your photos, along with any visible damage.
Cast coil equipment has windings encapsulated in solid resin, often recognizable as formed resin coils inside an enclosure. We buy cast coil transformers and medium-voltage dry-type equipment, including removed and unused units. Do not assume that every indoor transformer has the same voltage class or construction.
The nameplate is more useful than the cabinet size alone. Send the kVA rating, meaning kilovolt-amperes of electrical capacity, and the primary and secondary voltages—the input and output voltage ratings. Include impedance if listed; this describes the transformer's opposition to current flow and matters when evaluating its electrical characteristics.
Liquid-filled, step-up and renewable project transformers
Liquid-filled describes the insulation and cooling construction, not just the equipment's shape. Padmount, pole-mount, substation and power units may all use insulating liquid. We buy oil-filled transformers across these configurations; send the fluid information shown on the nameplate or available records.
We also buy step-up transformers, generator step-up units and transformers from renewable energy projects. A step-up transformer raises voltage; a generator step-up transformer, often called a GSU, connects generator output to a higher-voltage system. State the equipment's original application and include both voltage ratings rather than describing it only as a solar, wind or generator transformer.
For larger liquid-filled equipment, include available cooling ratings and test records. ONAN/ONAF identifies natural oil circulation with natural-air or fan-assisted air cooling. DGA, or dissolved gas analysis, is an oil test used to assess internal conditions. Existing records help describe the unit; send what you have.
New surplus, retired, failed and damaged transformers
We buy transformers that no longer fit a project as well as equipment that has reached the end of service. New surplus may include units still in crates or equipment delivered but never installed. Show packaging, storage condition and any available factory paperwork so we can distinguish unused equipment from previously operated units.
A failure does not automatically rule out an offer. We assess scrap, failed and damaged transformers, including units with visible damage or known operating problems. Describe what happened, identify missing components and photograph affected areas without opening or handling unsafe equipment.
If records identify PCB content, include them with your submission. PCB means polychlorinated biphenyls, substances associated with some older insulating fluids. Condition, completeness and documented fluid information help establish what is being offered and inform the agreed pickup details.
Send the details and agree on pickup
To sell electrical transformers, call or text (951) 403-5738, email Industrial832@gmail.com or request an offer for your equipment. Send a readable nameplate photo, overall photos, quantity, location and condition. For a whole lot, identify units individually where ratings or conditions differ.
Include available dimensions, weights and site-access information, especially for large units or equipment inside a building. Mention loading access and any constraints that could affect freight planning. We assess the details and respond with an offer.
Price, payment terms and pickup details are agreed in writing before anything is loaded. Disconnection and de-energizing stay with the seller or the seller's qualified electrical contractor. We work out trucking and load-out with you.
Frequently asked questions
Can you identify my transformer from photos?
Send an overall photo and a readable nameplate photo. The enclosure helps identify the category, while the nameplate supplies capacity, voltage and other details needed to assess the equipment.
Do you buy single-phase and three-phase transformers?
Yes. We buy both single-phase and three-phase equipment, including padmounts and other transformer configurations. Tell us the quantity and send each unit's ratings when the lot contains different equipment.
Does the transformer have to work?
No. We buy working, retired, failed and damaged transformers, as well as new surplus. Describe the condition and any known failure or missing parts when you submit the photos.
Can I sell equipment located outside Houston?
Yes. We buy anywhere in Texas from our Houston base and coordinate trucking and pickup. Provide the equipment's location and access details so those arrangements can be discussed.
What if I have several different transformer types?
Send the whole lot for assessment, with photos and quantities organized by unit or group. Separate nameplate photos help distinguish ratings, construction and condition without requiring you to classify every transformer first.
