Sell Siemens transformers from single units to whole lots
We buy Siemens and Siemens Energy transformers that are new in crate, used, working, retired or failed. Our buying scope runs from 10 kVA pole-mount units to large MVA substation and power transformers, with no requirement to assemble a full truckload. kVA means kilovolt-amperes; MVA means megavolt-amperes, equal to 1,000 kVA.
Whether you manage a plant replacement, a utility retirement or surplus from a canceled project, start with the equipment you have. As a Siemens transformer buyer based at 6402 McGrew St, Houston, TX 77087, we buy statewide and coordinate trucking and pickup with sellers throughout Texas.
- Single transformers removed from service or awaiting replacement.
- Whole lots of unused inventory, retired equipment or mixed-condition units.
- Failed transformers with a clear description of the fault and available records.
Siemens transformer types we buy
Siemens nameplates appear on substation, power, cast resin and dry-type transformers, as well as unit substation switchgear. Photograph the actual transformer rather than relying only on a nearby cabinet label. For a combined assembly, show the transformer and adjoining equipment separately.
We consider these transformer types for purchase. Include every unit in your inventory, even when ratings, conditions or nameplate brands differ.
- Substation transformers, including retired units and replacements left over after a project.
- Large power transformers rated in MVA, with available operating and maintenance records.
- Cast coil transformers, including cast resin and medium-voltage dry-type equipment.
- Unit substation assemblies, with photos showing the transformer and close-coupled switchgear.
- Dry-type transformers, whether unused surplus, working equipment or failed units.

Find the serial number, manufacturing date and ratings
Take a straight-on, readable photo of the Siemens transformer nameplate. Look for the plate on the tank, enclosure or frame, using only safely accessible areas. Do not open energized compartments to obtain a photo; have your qualified electrical contractor handle access that requires electrical work.
Locate the serial number and any field labeled date of manufacture, year or equivalent wording. Copy those entries exactly as shown rather than estimating from appearance. If the date is absent or unreadable, send the plate photo and state that the manufacturing date is unknown.
Capture the capacity, primary and secondary voltage, phase, frequency and impedance. Primary voltage is the incoming supply rating; secondary voltage is the output rating. Impedance is the transformer’s opposition to current flow, usually expressed as a percentage, and helps identify whether a unit suits a particular installation.
Include cooling designations such as ONAN or ONAF if shown: these describe oil and air cooling arrangements, with natural air cooling or fan-assisted air cooling. Our guide to reading a transformer nameplate helps you identify the fields without guessing.
Legacy Siemens and current Siemens Energy nameplates
Siemens Energy became a separate company in 2020 and carries the large power transformer business. Equipment offered for sale may therefore bear Siemens or Siemens Energy identification. Send the nameplate as it appears; there is no need to relabel the equipment or decide which business name applies.
A Siemens label on a switchgear section does not by itself establish the identity or ratings of the adjoining transformer. Siemens switchgear lineups are frequently close-coupled to transformers in unit substations. Photograph each relevant nameplate and provide an overall view showing how the sections connect.
For older equipment, records can help fill gaps left by faded labels. Include available drawings, test reports or asset records, and distinguish documented information from an estimate. Nameplate branding alone should not be treated as proof of manufacturing date.
How age and condition affect an offer
Age is one part of the assessment, not a substitute for ratings and condition. Used Siemens transformers with readable identification and a documented operating history are easier to evaluate than units with unknown ratings or unexplained damage. New-in-crate equipment also needs photos showing storage condition and what is included.
Tell us about leaks, corrosion, cracked insulation, missing parts, fire exposure or a known electrical failure. For dry-type equipment, show the enclosure and safely accessible winding areas. For liquid-filled units, include available oil test results or DGA reports; DGA means dissolved gas analysis, a test used to help assess internal condition.
If records identify PCB status, include them with the submission. PCB refers to polychlorinated biphenyls, chemicals relevant to handling some older insulating fluids. Ratings, completeness, condition, documentation and load-out requirements all help inform the offer; our used transformer value guide explains the assessment factors.
What to send for a Siemens transformer offer
To sell Siemens transformers, send enough information to identify the equipment and plan its removal. Call or text (951) 403-5738, email Industrial832@gmail.com, or submit your transformer details. We evaluate the information and respond with an offer.
- A readable nameplate photo for each distinct unit or rating.
- Overall photos from several sides, plus visible damage and included accessories.
- Quantity, current location and whether the equipment is installed or already removed.
- Condition, known faults and available test or maintenance records.
- Access details, approximate weight if documented, and available loading arrangements.
Pickup and load-out anywhere in Texas
We coordinate freight and load-out with the seller from our Houston base. Price, payment terms and pickup details are agreed in writing before anything is loaded. Share access restrictions, lifting information and whether adjoining switchgear or other structures affect removal.
The unit has to be de-energized and disconnected by the seller or the seller's qualified electrician. For Siemens dry-type surplus already in storage, show whether it is crated, palletized or loose. For installed unit substations, identify which sections are included so the pickup plan matches the agreed sale.
Frequently asked questions
Can I sell a failed Siemens transformer?
Yes. We buy failed units as well as working transformers. Describe the failure and send photos of damage, the nameplate and any available test records.
Do you buy Siemens Energy power transformers?
Yes. We buy Siemens Energy power transformers, including large MVA units. Send the ratings, condition, location and available weight or transport information.
Is an older Siemens transformer worth submitting?
Yes. Send its nameplate and condition details rather than ruling it out by age alone. We consider retired equipment, single units and whole lots.
What if the nameplate is missing or unreadable?
Send the clearest photos you can, along with drawings or asset records. Identify unknown ratings plainly instead of guessing.
Can you arrange pickup outside Houston?
Yes. We buy statewide across Texas and coordinate trucking and pickup. Provide the site location and loading access details with your submission.
