500 kVA Transformer Buyers

500 kVA transformer buyers for New York facilities

We buy individual 500 kVA transformers and groups of units from facility upgrades, plant closures, electrical service replacements and surplus inventories. At this size, we commonly review outdoor padmount transformers and substation transformers serving commercial buildings, industrial facilities and larger property developments. We also buy indoor dry-type units removed during distribution-system changes.

In New York, a 500 kVA transformer may supply a warehouse, manufacturing area, apartment property's customer-owned distribution system or commercial building. Its rating describes apparent power capacity, not the building's actual demand or the amount of usable motor load in every installation. We need the nameplate rather than a description of the building alone.

Our reviews of padmount transformers focus on the cabinet, terminations, fluid compartment and nameplate configuration. For substation transformers, include photos of bushings, connection chambers and any attached throat or enclosure. Tell us which components are included in the sale.

Confirm ownership before requesting an offer. A utility-owned transformer belongs to the utility and is not yours to sell merely because it sits on your property.

Full-load amps for a 500 kVA transformer

Calculated as kVA × 1,000 ÷ (1.732 × V) for a three-phase unit. Check the nameplate for the actual ratings. Use the kVA to amps calculator.

Voltages and full-load amps at 500 kVA

Common three-phase configurations include medium-voltage primaries such as 12,470 V, 13,200 V or 13,800 V, with secondaries such as 480Y/277 V or 208Y/120 V. We also review units with other primary voltages, including 4,160 V and 34,500 V. The exact winding connections, taps and voltage ratings matter when we assess a unit for reuse.

Send a readable photograph of the complete nameplate. A description such as “500 kVA, 480 volts” leaves out the primary voltage, phase, connection and other details needed to identify the transformer. For dry-type transformers, include the enclosure rating and insulation information shown on the plate.

The template's full-load amps table shows calculated three-phase current at each listed line-to-line voltage. At 500 kVA, the values are 601.4 A at 480 V, 1387.9 A at 208 V and 23.1 A at 12,470 V. These are rated-current calculations, not measurements of the transformer's present load.

Our kVA-to-amps calculator explains the relationship. Conductor, protection and installation decisions require more information than this calculation; confirm applicable requirements with the project's electrical professional.

Approximate 500 kVA transformer weight and oil volume

For preliminary planning, many oil-filled 500 kVA padmount and substation transformers fall in an approximate total-weight range of 3,500–8,000 pounds. Oil volume may be roughly 100–250 gallons. These are broad planning ranges, not specifications for your transformer: check the nameplate and manufacturer documentation for the actual weight and fluid quantity.

Construction changes both figures. Copper or aluminum windings, tank design, radiators, cabinet size and attached connection compartments affect the load being moved. Dry-type units contain no insulating oil and need their own documented weight rather than an estimate borrowed from an oil-filled model.

When asking about the weight of a 500 kVA transformer, distinguish total operating weight from shipping weight or a weight stated without fluid. Tell us if oil has been removed or if cabinets, radiators or other transformer components have been detached.

Our transformer weight guide provides general planning context. We use the unit's documented weight, dimensions, lifting provisions and site conditions to coordinate pickup; an approximate range alone is not enough to select lifting equipment.

What drives a used 500 kVA transformer's resale value

We assess a used 500 kVA transformer by its potential for reuse, its condition and the practical cost of moving it. A complete unit with a readable nameplate, useful voltage configuration and documented operating history gives us more to evaluate than an unidentified tank. New-in-crate surplus should include crate photos and any storage or factory documentation available.

The details that help us prepare a written offer include:

• Primary and secondary voltages, phase, winding connections and tap settings.
• Manufacturer, serial number, age and complete nameplate information.
• Whether it was working when disconnected, and why it was removed.
• Available test reports, maintenance records and fluid information.
• Leaks, corrosion, damaged bushings, missing parts or known electrical faults.
• Pickup location, access restrictions and loading arrangements.

We buy failed and scrap units too, but evaluate them differently from equipment suitable for reuse. Do not describe a unit as tested unless you have results to support that description.

Our guide to what a used transformer is worth explains the main evaluation factors. We make an offer for the actual unit and pickup conditions, not from kVA alone.

Fluid identification and photos to send with your request

For an oil-filled unit, tell us whether the insulating fluid is mineral oil, FR3 or another natural ester, or silicone. Send photographs of fluid labels and any PCB-status markings, along with available laboratory reports. If the fluid type or PCB status is unknown, state that clearly rather than guessing from the transformer's age or appearance.

PCB status can affect handling, transportation and disposition. Confirm current requirements with the appropriate environmental professional or agency; do not drain or sample a transformer just to prepare an offer without qualified assistance.

A useful photo set includes the full nameplate, all accessible sides, the cabinet or connection compartments, visible damage and the surrounding pickup area. Photograph the route to the truck as well, especially if the transformer sits behind a fence, inside a building or below grade. Only photograph energized or enclosed equipment from safe, authorized positions.

Use our online offer form, or call or text 951-403-5738 with the photos and location. Tell us whether the unit remains installed, has been disconnected or is already staged for loading.

How we coordinate pickup for a 500 kVA transformer

Once we agree on a written offer, we plan pickup around the transformer's documented weight and dimensions, the available lifting points and the truck's access to the site. We coordinate rigging, a suitable forklift or crane, and flatbed, step-deck or lowboy transportation as the load requires. You can also handle loading if that arrangement is agreed in advance.

For padmount units, describe the pad, surrounding pavement, overhead obstructions and distance from the truck position. For indoor or substation units, provide doorway dimensions, route restrictions and details of attached transformer compartments. Let us know about loading docks, gates, restricted pickup hours or limited staging space before scheduling.

Equipment must be safely disconnected and released for removal by the responsible parties before loading. At pickup, we make a quick inspection to confirm that the transformer matches the photos and agreed description, then handle payment by check, ACH or wire under the agreed terms.

Our buying process explains these steps. We coordinate pickup throughout our New York service area; we have no public storefront or drop-off yard in the state.
