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 333 kVA class
A 333 kVA rating describes apparent power, not the transformer’s voltage or physical dimensions. For the three-phase padmount considered here, record the full nameplate rather than relying on a painted enclosure label.
Include manufacturer, serial number, frequency, impedance and winding connection in the equipment record.
Check whether 333 kVA identifies the complete three-phase unit or an individual single-phase transformer within a bank. Those are different removal scopes.
A photograph showing the rating, phase designation and connection diagram helps resolve the distinction before anyone counts tanks, cable compartments or lifting points.
Local reality
Typical North Carolina applications
A three-phase 333 kVA padmount can serve a mid-size industrial service with motors, ventilation equipment and production loads. At a Piedmont plant, useful records include the service one-line, connected voltage and ownership boundary.
The transformer beside the loading dock may belong to the utility, not the facility.
For a retired service in Charlotte, Greensboro or eastern North Carolina, identify what remains energized before planning removal. Secondary conductors may share a trench with active circuits.
Hospital facilities staff should also check transfer-switch drawings, since normal service and generator distribution can occupy closely spaced electrical yards.
Around the site
Shipping weight and footprint
Typical shipping weight for this 333 kVA equipment is roughly 2,600 to 3,900 pounds. Use that band for preliminary planning only.
The nameplate, certified drawing or manufacturer’s weight record should govern transport arrangements, especially when radiators, cable boxes or other attached components change the load envelope.
Measure tank width, enclosure depth and overall height, including bushings and any protruding fittings. A 333 kVA rating does not establish one standard footprint.
Record the concrete pad dimensions and door swing, then measure the route past bollards, fences and overhead obstructions to the planned loading position.
Where it sits
Rigging and load-out
A 20-ton crane is a handling option for a 333 kVA unit, but its nominal capacity does not approve the lift. The operator must check the load chart at the actual radius, boom configuration and outrigger setup.
Pavement condition and underground structures also affect where the crane can stand.
Oil weight is approximately one-third of the total for the equipment described here, so confirm whether the recorded weight includes fluid. Use designated lifting points and suitable rigging; a spreader bar may prevent sling contact with bushings.
Plan containment, truck access and securement before the tank leaves the pad.
On the ground
Primary and secondary voltages
Record both voltage ratings exactly as the 333 kVA nameplate shows them. North Carolina industrial services may involve a 12,470-volt primary and a 480Y/277-volt secondary, but those values are examples, not specifications for every unit.
Photograph the tap table and note the documented operating tap position.
For a verified three-phase 333 kVA transformer, rated secondary current is about 400 amperes at 480 volts, or 924 amperes at 208 volts. These calculations do not establish conductor sizing or protective settings.
Include the winding diagram, grounding arrangement and bushing markings so the electrical configuration remains identifiable after disconnection.
Local reality
Inspection and oil test
Inspect the 333 kVA tank for gasket leaks, radiator damage, corrosion at the base and evidence of overheating near terminations. Photograph bayonet fuse hardware and elbow interfaces where fitted.
Qualified personnel should establish isolation and verify absence of voltage before opening compartments or examining exposed electrical connections.
An oil report should identify the 333 kVA unit by serial number, sampling date and laboratory results. Useful records include dielectric breakdown, moisture and dissolved gas testing where applicable. Provide PCB documentation separately; tank appearance cannot establish PCB status.
Disclose internal faults, water entry and any previous fluid replacement.
Around the site
Valuation for this size
Assessment of a 333 kVA transformer starts with its verified identity and condition. A readable nameplate, complete winding connections and documented oil condition allow a more definite review than an unidentified tank.
State whether the unit was removed during a service upgrade, after a fault or during demolition.
Removal conditions also matter: a 2,600-to-3,900-pound unit on an accessible pad presents a different scope from one behind a building with restricted crane reach. Transformer Buyers NC buys these units across North Carolina.
Provide ownership authorization, disconnect status, dimensions and photographs of the tank, pad and access route.

Questions
Straight answers
Equipment types
Can you buy a failed 333 kVA transformer?
Yes. Transformer Buyers NC buys failed 333 kVA transformers as well as used, surplus and obsolete units. Describe the failure, including a winding fault, leaking tank or damaged bushing.
Service area
Does every 333 kVA unit need a 20-ton crane?
No single crane designation establishes a safe lift. A 20-ton crane is a handling option, subject to the actual lifting radius and load chart.
Payment
What records identify my 333 kVA transformer correctly?
Provide a readable nameplate photograph, serial number, phase designation, primary and secondary voltages, and winding diagram. Include oil test reports and ownership authorization where available. Confirm whether 333 kVA describes one complete three-phase padmount or a single-phase unit belonging to a larger transformer bank.
Logistics
Primary and secondary voltages: what should a seller know?
Record both voltage ratings exactly as the 333 kVA nameplate shows them. North Carolina industrial services may involve a 12,470-volt primary and a 480Y/277-volt secondary, but those values are examples, not specifications for every unit.
