What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete Siemens transformers anywhere in North Carolina. This page covers their construction, common deterioration, nameplate records and removal requirements for plant engineers, utility asset managers, facility directors, contractors and trustees.
For a Siemens unit leaving a Charlotte plant or a hospital electrical room in Raleigh, identification starts with the serial number, test certificate and installed cooling equipment—not the badge alone.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|

| 3-phase | 15 kVA - 20 MVA | up to 230 kV | Liquid or dry |

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
Siemens's design signature
Siemens is a German manufacturer with a long record in distribution and power transformers, plus a large dry-type line. Its design signature includes tight tolerances and modular cooling. Those details matter when identifying a disconnected unit beside a North Carolina plant.
Documentation is another Siemens characteristic: records can survive the plant where the equipment was installed. A retained test certificate helps connect the serial number to original electrical performance. Cooling drawings can distinguish an intended radiator arrangement from equipment modified during later maintenance.
Local reality
The Siemens units we see in North Carolina
A Siemens assessment in North Carolina may involve an outdoor liquid-filled distribution unit, a larger power transformer or a dry-type assembly inside a facility. Each requires different access information: pad clearance outdoors, radiator clearance in a yard or door dimensions indoors.
For a dry-type Siemens transformer in a Raleigh hospital, removal planning starts with the enclosure dimensions and the route out of the electrical room. At a Piedmont industrial site, an outdoor unit instead requires checks of bushings, attached cooling equipment and pad access.

Known failure modes
Winding insulation aging deserves particular attention on Siemens units past 30 years. Age alone does not establish failure, but operating history and test records become important. Reports of overheating, protection trips or declining insulation readings should remain with the serial-number documentation during assessment.
Outdoor Siemens enclosures can develop hardened gaskets after years of exposure. Inspect cover seams, bushing flanges and radiator connections for leakage or staining. A dry surface during one visit does not resolve the history; maintenance notes may document leaks that were cleaned or repaired.
Where it sits
Reading a Siemens nameplate
Photograph the complete Siemens nameplate squarely enough to read the serial number, rated kVA or MVA, primary and secondary voltages, impedance and cooling class. Include tap information where shown. A close photograph of the badge alone cannot establish the unit's electrical configuration.
Compare the plate with the Siemens test certificate rather than transcribing one record in isolation. Serial numbers must identify the same unit. If a North Carolina facility changed fans, controls or radiator assemblies, note those alterations separately instead of treating them as original construction.
On the ground
What we check on site
On site, we check the Siemens test certificate, the stated impedance and whether the cooling class matches the nameplate. Installed fans and cooling controls need to support that identification. Missing equipment or disconnected wiring gets recorded, not assumed to be a minor omission.
Physical inspection follows the paperwork: tank seams, hardened gaskets, bushings, radiator attachments and accessible enclosure surfaces. For liquid-filled Siemens equipment, fluid records and applicable PCB documentation also matter.
Electrical isolation must be confirmed by qualified site personnel before inspection enters restricted or exposed areas.
Local reality
Transport and rigging notes
A Siemens power transformer with modular cooling needs a removal plan that distinguishes the main tank from detachable radiators and accessories. Confirm transport weight from drawings or other reliable records. Lift points must be identified for the actual assembly, not inferred from nearby brackets.
At a North Carolina plant, truck access can decide whether a lowboy reaches the pad or needs a separate loading position. Document overhead obstructions, turning space and ground conditions. For Siemens dry-type units, check the doorway and rigging route before removing enclosure panels.
Around the site
What the badge does to value
The Siemens badge establishes a manufacturer, not a complete assessment. A readable nameplate and matching test certificate establish much more: configuration, impedance and original test information. Those records help distinguish a documented surplus unit from a failed transformer with an uncertain service history.
Condition still governs how a Siemens unit is evaluated for removal and recovery. A sound enclosure does not prove sound winding insulation, especially beyond 30 years.
Missing radiators, hardened gaskets and undocumented modifications must be considered alongside the manufacturer's identification and available technical records.

Questions
Straight answers
Equipment types
Do you buy failed Siemens transformers in North Carolina?
Yes. Transformer Buyers NC buys failed Siemens transformers anywhere in North Carolina, along with used, surplus and obsolete units. Describe the failure, provide readable nameplate photographs and retain any test reports. Winding insulation problems and outdoor gasket leaks should be identified separately.
Service area
Which Siemens documents should stay with the unit?
Keep the test certificate, nameplate photographs, cooling drawings and maintenance reports together under the Siemens serial number. Include records of fan or radiator changes. For liquid-filled equipment, retain fluid testing and applicable PCB documentation rather than relying on an unverified description.
Payment
Can a Siemens dry-type unit leave an indoor room?
Removal depends on dimensions, weight and a verified rigging route. For a Siemens dry-type transformer in a North Carolina facility, measure doors, corridors and overhead clearance. Qualified personnel must complete electrical isolation, and the lifting plan must address the actual assembly.
Logistics
The Siemens units we see in North Carolina: what should a seller know?
A Siemens assessment in North Carolina may involve an outdoor liquid-filled distribution unit, a larger power transformer or a dry-type assembly inside a facility. Each requires different access information: pad clearance outdoors, radiator clearance in a yard or door dimensions indoors.
