2500 kVA Transformer Buyers for Padmount and Substation Units
At 2500 kVA, or 2.5 MVA, we commonly review three-phase padmount and substation transformers. These units serve substantial building and process loads, so the enclosure, terminal arrangement, and voltage configuration matter as much as the rating. We buy one surplus transformer or multiple units released by a project or facility closure.
For 2500 kVA padmount transformers, send pictures of the cabinet exterior and any safely accessible compartment labels. Useful details include dead-front or live-front construction, loop-feed or radial-feed arrangement, and the primary connection setup. Do not open energized compartments to obtain photos.
For substation transformers, show the bushings, terminal chambers, radiators, and connection to adjoining switchgear. Tell us what remains attached and what has already been disconnected. If yours is one of the dry-type transformers we buy, include enclosure photos and cooling information instead of oil details. In every case, we need a readable nameplate and confirmation that you own or are authorized to sell the unit.

New York Applications and Voltage Configurations
A used 2500 kVA transformer may become available after a manufacturing line closes, a commercial facility changes its electrical service, or a developer replaces equipment during redevelopment. This size also appears in larger institutional facilities and renewable-energy projects. We review the actual configuration rather than treating every 2.5 MVA unit as interchangeable.
Primary voltage ratings you may encounter include 4,160, 12,470, 13,200, 13,800, and 34,500 volts. Secondary configurations may include 480Y/277 volts, 208Y/120 volts, 600 volts, or medium-voltage outputs such as 4,160 volts. These are examples, not a compatibility checklist: send the complete primary and secondary ratings, winding connections, frequency, impedance, and tap information from the nameplate.
Tell us if the transformer supplied a building, industrial process, or generation interconnection. That context helps us understand its previous service, but we base our review on the equipment itself. A utility-owned transformer belongs to the utility and is not yours to sell simply because it sits on your property.
2500 kVA Transformer Full Load Amps
The full-load amps table on this page shows calculated three-phase current at several voltages. For a 2500 kVA transformer, the listed values include 3007.0 A at 480 V, 347.0 A at 4160 V, and 115.7 A at 12470 V. These calculations use line-to-line voltage and the three-phase relationship between apparent power, voltage, and current.
The primary and secondary carry different currents because their voltages differ. A unit rated 12,470 volts primary and 480 volts secondary therefore has a much lower calculated primary current than secondary current. Our kVA-to-amps calculator explains the calculation if you are comparing other ratings or voltages.
For an offer, send the nameplate rather than only an amperage figure. We need to verify the rated kVA, phase, voltage, and any cooling-dependent ratings together. The table is a reference for calculated rated current; it is not a measurement of the facility's operating load or a substitute for electrical design information.
Approximate Weight and Oil Volume for Pickup Planning
For initial planning, a liquid-filled 2500 kVA padmount or compact substation transformer may weigh approximately 10,000–22,000 pounds and contain roughly 400–900 gallons of insulating fluid. These are broad estimates, not shipping specifications. Check the nameplate and manufacturer documentation for the actual total weight and fluid quantity; some designs fall outside these ranges.
The weight of a 2500 kVA transformer depends on its construction, voltage class, enclosure, cooling arrangement, and accessories. A total operating weight may include fluid, while a shipping weight may reflect a different configuration. Tell us exactly which weight is listed and whether radiators, terminal chambers, or other parts have been removed. Our transformer weight guide provides additional planning context.
Send the overall dimensions and photos of lifting points, the base, and the approach to the unit. Identify mineral oil, FR3 or another natural ester, or silicone fluid when documented, and provide available PCB information. Keep fluid contained and confirm current handling requirements with the appropriate qualified parties before removal.
What Drives Resale Value at 2500 kVA
When you want to sell a 2500 kVA transformer, we first assess its suitability for reuse. Voltage configuration, winding material when documented, age, condition, impedance, accessories, and available test records all contribute to our review. A readable nameplate lets us identify the unit accurately instead of relying on cabinet appearance or an estimated rating.
Condition details should be specific. Tell us about leaks, damaged bushings, corrosion, missing components, or an electrical failure. If the unit operated normally before removal, say when it was disconnected and how it has been stored. For new surplus, show the crate, manufacturer labels, and any evidence of storage damage.
Useful supporting information includes:
- Factory or recent electrical test reports, if available.
- Oil test results and documented fluid or PCB status.
- Photos of terminals, radiators, gauges, and visible damage.
- A list of included accessories and removed parts.
We also consider failed and scrap units. Our guide to what a used transformer is worth explains the broader factors; we provide a written offer after reviewing your specific equipment and pickup requirements.
How We Arrange Pickup of a 2.5 MVA Transformer
Call or text 951-403-5738, or submit your 2500 kVA transformer for an offer with nameplate photos, condition, dimensions, and location. Tell us whether the unit is still installed, already disconnected, or sitting in storage. Include gate restrictions, overhead obstructions, loading space, and any deadline for clearing the site.
After reviewing the details, we provide a written offer and agree on pickup responsibilities. For a unit this size, we coordinate suitable rigging, forklift or crane access, and flatbed, step-deck, or lowboy trucking. You can load the transformer if you prefer, with the loading plan agreed in advance. Electrical disconnection must be completed safely by qualified personnel before loading.
At pickup, we make a quick inspection to confirm that the unit matches the photos and description. Payment is by check, ACH, or wire under the agreed terms. Our transformer buying process explains the sequence. We coordinate pickup across our New York State service area; we do not operate a public storefront or drop-off yard in New York.
Questions sellers ask about 2500 kVA
Who buys used 2500 kVA transformers in New York?
We buy used 2500 kVA transformers anywhere in New York State, including padmount and substation units. We also review new surplus, removed-from-service, damaged, failed, and scrap units. Send readable nameplate photos, condition details, and the pickup location so we can evaluate the transformer and provide a written offer.
How many amps is a 2500 kVA transformer at 480 volts?
A three-phase 2500 kVA transformer has a calculated full-load current of 3007.0 A at 480 volts line-to-line. Current changes with voltage, so that figure applies to the 480-volt side, not every winding. Check the nameplate for the transformer's actual voltage, phase, and rating before using calculated current for planning.
How much does a 2500 kVA transformer weigh?
A liquid-filled 2500 kVA padmount or compact substation unit may weigh approximately 10,000–22,000 pounds, but designs vary and some fall outside that range. Check the nameplate or manufacturer documentation. For pickup, we need the actual weight, dimensions, fluid status, and details of any components removed from the unit.
Can I sell a failed 2500 kVA transformer with oil still inside?
We consider failed liquid-filled transformers as well as units suitable for reuse. Tell us what failed, whether the tank leaks, the fluid type and quantity, and the documented PCB status. Do not drain the transformer just to prepare an offer request; we review its condition and agree on handling and pickup requirements first.
