Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed, and obsolete 150 kVA transformers anywhere in North Carolina. This page covers the three-phase padmount commonly serving an apartment building or warehouse office, including identification, inspection, and removal.

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
The 150 kVA class
A 150 kVA nameplate describes apparent-power capacity, not the connected building load. On a three-phase padmount, confirm that the rating belongs to the complete unit rather than one transformer in a bank.
Photograph the nameplate, serial number, connection diagram, and tap positions before the enclosure leaves its pad.
An apartment service transformer may have separable primary elbows behind one compartment door and secondary cable terminals behind another. Dry-type 150 kVA units also appear inside North Carolina buildings, but their enclosures, insulation systems, and lifting arrangements differ.
Identify liquid-filled versus dry-type construction before planning inspection or removal.
Local reality
Typical North Carolina applications
At a Raleigh apartment building, a 150 kVA three-phase padmount may serve common-area equipment or a defined portion of the electrical service. The actual assignment comes from the one-line diagram and panel schedules.
Do not assume that the transformer feeds every dwelling simply because it sits beside the building.
A warehouse office in Greensboro may use this class for lighting, receptacles, HVAC, and small support loads while larger equipment has separate service. Before offering the transformer, establish ownership from utility records or project documents.
A pad inside the property line does not prove that the building owner owns it.
Around the site
Shipping weight and footprint
Shipping weight for the specified 150 kVA padmount is roughly 1,300 to 2,000 pounds. Treat that band as an initial planning figure, not a lifting authorization.
The manufacturer's nameplate or drawing should establish actual weight, including insulating liquid, before selecting rigging and checking the truck's permitted payload.
Measure the tank and cabinet together, including projecting hinges, handles, and any radiators. A 150 kVA unit can fit a conventional truck without requiring a lowboy, but deck height and securement still matter.
Record the pad dimensions, gate opening, and overhead clearance along the route to the loading position.
Where it sits
Rigging and load-out
A 15-ton crane is suitable for planning this 150 kVA removal, subject to its load chart at the actual working radius. Crane capacity changes with boom length and setup.
Give the operator the confirmed weight, lift-point photographs, pad location, and distance from the proposed outrigger position to the tank.
With this roughly 1,300-to-2,000-pound unit, a lowboy is not needed. Use rated lifting provisions and protect bushings from sling contact; a spreader bar may be appropriate for the manufacturer's arrangement.
Qualified personnel must isolate, verify absence of voltage, and disconnect the transformer before the crane takes its weight.
On the ground
Primary and secondary voltages
A 150 kVA padmount may carry a primary rating such as 12,470 grounded-wye/7,200 volts, but the nameplate must settle the actual configuration. North Carolina service arrangements vary by utility and location.
Record primary voltage, tap range, BIL, and whether the primary compartment uses loop-feed or radial-feed connections.
A 208Y/120-volt secondary fits many apartment common-area and warehouse-office loads; 480Y/277 volts is another possible configuration. At 150 kVA, rated three-phase secondary current is approximately 416 amperes at 208 volts or 180 amperes at 480 volts.
Photograph the secondary terminals and winding diagram rather than inferring voltage from cable size.
Local reality
Inspection and oil test
Inspect a liquid-filled 150 kVA tank for oil tracks below bushings, wet cabinet seams, damaged gaskets, and corrosion near the concrete pad. Record missing elbows, broken terminals, and any bayonet fuse operation.
A failed fuse alone does not establish whether the fault occurred inside the winding or downstream.
For an oil-filled 150 kVA unit, provide existing oil test reports with sample date, serial number, and laboratory identification. Useful records may include dielectric breakdown, moisture, dissolved gas analysis, and PCB results where applicable.
Do not open a sealed tank or take a sample without qualified personnel and appropriate procedures.

Valuation for this size
Assessment of a 150 kVA transformer begins with its nameplate and condition, not its weight alone. Voltage combination, conductor material, age, intact bushings, and documented operating history distinguish a reusable unit from one requiring material recovery.
A winding fault and a leaking gasket require different technical evaluations before removal.
For a North Carolina removal, the assessment also needs ownership documentation, oil records, photographs, and access details. Note whether the 150 kVA tank remains connected, whether a crane can reach the pad, and whether the cabinet contains loose cables.

Questions
Straight answers
Equipment types
How much does a 150 kVA padmount weigh?
The specified three-phase padmount typically weighs roughly 1,300 to 2,000 pounds for shipping. Confirm the actual weight from its nameplate or manufacturer's drawing. Include the insulating liquid and attached cabinet when giving the crane operator and truck carrier the load information.
Service area
Does this transformer need a lowboy for removal?
A lowboy is not needed for this 150 kVA unit. A conventional truck can handle the shipment when payload, deck dimensions, and securement are suitable. A 15-ton crane must still be checked against its load chart for the actual radius and setup.
Payment
Can you buy a failed 150 kVA transformer?
Transformer Buyers NC buys failed 150 kVA transformers as well as used, surplus, and obsolete units. Document the failure, including winding damage, bushing breakage, leaks, or fuse operation. Provide the nameplate, ownership records, and available oil reports before planning disconnection and pickup.

Primary and secondary voltages: what should a seller know?
A 150 kVA padmount may carry a primary rating such as 12,470 grounded-wye/7,200 volts, but the nameplate must settle the actual configuration. North Carolina service arrangements vary by utility and location.
