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
What makes a Delta Star different
Delta Star is a Virginia manufacturer of power transformers and mobile substations. Its mobile packages require a broader review than a transformer tank alone.
The trailer, switchgear, bushings, cooling equipment and connection arrangements can all affect how a retired package is handled in North Carolina.
Heavy Delta Star power units also call for close attention to documentation. A factory test report, outline drawing and transport drawing can establish details that yard photographs cannot.
Those records help distinguish the operating assembly from the shipping arrangement, especially when radiators and bushings travel separately.
Local reality
Delta Star vintages and models in the state
A Delta Star assessment starts with the serial number and manufacturing date, not an assumed model family. North Carolina owners may be retiring a stationary power transformer or a mobile substation package.
Photographs should establish which assembly is present before anyone plans a lift or tow.
Older Delta Star equipment may have replacement bushings, modified cooling controls or a trailer configuration different from the original drawing. Compare the present assembly with dated maintenance records.
For a mobile unit, record both the transformer identity and the trailer identification rather than treating them as interchangeable.
Around the site
Where they fail
Bushing and cooling failures deserve particular attention on Delta Star mobile units that have been moved frequently. Inspect porcelain, terminal connections, radiator attachments and fan assemblies for damage.
Movement history matters: repeated relocation can leave a different inspection trail than years of service on one concrete pad.
A failed Delta Star mobile package needs a clear account of the last event. Record whether a bushing flashed over, a fan stopped, a radiator leaked or protection operated.
Keep relay records and oil test results with the equipment; visible damage alone does not establish winding condition.
Where it sits
The nameplate and the paperwork
Photograph the Delta Star nameplate straight on, with voltage ratings, kVA or MVA rating, impedance, cooling designation and serial number readable. Include separate plates on the mobile trailer and associated switchgear.
A distant photograph of the whole package cannot replace legible identification of its principal components.
The test report is a priority document for a Delta Star review. Match its serial number to the tank, then collect outline drawings, transport instructions and maintenance records.
For oil-filled equipment, include available oil analysis and PCB documentation without assuming that age alone establishes fluid status.
On the ground
Inspection priorities
Completeness comes first on a Delta Star mobile substation. Identify missing bushings, radiator sections, fans, cable connections, control cabinets and switchgear components. Photograph detached parts beside their markings.
A package parked after an outage may look assembled while essential connection hardware sits elsewhere in the utility yard.
Next, compare the Delta Star transport configuration with its current condition. Check removable bushings, radiator isolation points, shipping covers and documented lifting locations. Inspect the trailer structure and running gear separately.
A complete electrical package does not establish that the trailer is ready for a highway move.
Local reality
Getting a Delta Star out of the building
For a Delta Star power unit inside a North Carolina plant, measure the doorway, overhead clearance and route to the loading area. Use the outline drawing to check tank dimensions against actual obstructions.
Radiator removal may change clearance, but only the documented configuration should guide that decision.
Outdoor removal needs the same discipline. A Delta Star mobile package may require trailer assessment, while a stationary unit may need a lowboy and engineered rigging. Confirm shipping weight, lifting provisions, crane access and ground conditions.
Electrical isolation and release remain the owner's responsibility before removal begins.
Around the site
How the brand affects our buying decision
The Delta Star name identifies the manufacturer, but the assessment rests on the actual unit. A documented power transformer and a partly stripped mobile package present different handling requirements.
Completeness, the test report and the transport configuration carry more useful information than a brand photograph by itself.
For North Carolina owners, the clearest submission includes Delta Star nameplate photographs, the latest test records, an equipment location and views of the removal route. State whether the unit is energized, isolated or damaged.
That information supports a buying review without confusing electrical condition with transport readiness.

Questions
Straight answers
Equipment types
Do you buy incomplete Delta Star mobile substations?
We review incomplete Delta Star mobile packages as well as complete assemblies. Identify missing switchgear, bushings, radiators, controls and trailer components. Include photographs of detached parts and any assembly drawings so the review accounts for what remains at the North Carolina site.
Service area
Which Delta Star documents should an owner gather?
Start with readable nameplate photographs and the matching test report. Add outline drawings, transport instructions, maintenance records and available oil analysis. For a mobile substation, include trailer identification and records of modifications that changed the original electrical assembly or shipping configuration.
Payment
Can a failed Delta Star unit be reviewed?
Yes. We buy failed Delta Star transformers, including mobile units with bushing or cooling damage. Describe the failure event and preserve relay records, test results and photographs. Do not energize damaged equipment for the review; document its present isolation status and physical condition.
