5000 kVA Transformer Buyers

5000 kVA Transformer Buyers for Padmount and Substation Units

We buy 5000 kVA transformers in padmount and substation configurations, including one surplus unit or multiple units from a facility shutdown. At this rating, three-phase liquid-filled equipment is common. We also review dry-type units when the rating, voltages and condition fit a reuse opportunity.

Large padmount transformers have enclosed cable compartments and are commonly installed outdoors on concrete pads. Substation transformers may have exposed bushings, enclosed terminals or connections to adjacent switchgear. Photos of both connection sides help us understand what is included and what has already been disconnected.

In New York, a 5 MVA transformer may serve a manufacturing plant, hospital campus, large commercial property or renewable-energy installation. We coordinate pickup across our New York service area, including sites where the transformer remains on its original pad. If the unit belongs to a utility, the property owner cannot sell it; confirm ownership before requesting an offer.

Full-load amps for a 5000 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.

Voltage Ratings and Connections We Need to Review

Common primary ratings for this size include 12,470, 13,200, 13,800 and 34,500 volts. Secondary ratings may include 480, 600 or 4,160 volts, depending on the installation. A renewable-energy step-up transformer may use these voltage levels in the opposite power-flow direction, so send the complete nameplate rather than describing only the site service voltage.

We review the winding connections, frequency, impedance, taps and cooling designation along with the kVA rating. Delta and grounded-wye connections affect compatibility with a buyer’s system. A transformer with multiple cooling ratings needs a clear nameplate photo showing whether 5000 kVA is its base rating or a rating that depends on operating fans.

Include photos of bushings, cable compartments, tap controls and any attached cooling equipment. If your yard contains mixed ratings, our transformer size pages can help you separate the inventory before submitting it. List each unit individually rather than treating similar-looking tanks as identical equipment.

5000 kVA Transformer Full Load Amps

The full-load amps table on this page shows calculated three-phase current at several voltages. For a 5000 kVA transformer, the values include 480 V = 6014.1 A, 4160 V = 693.9 A and 13800 V = 209.2 A. These are winding-current calculations at the stated voltage, not measurements of the transformer’s actual operating load.

The three-phase calculation is rated VA divided by the square root of three times line-to-line voltage. Our kVA-to-amps calculator explains the relationship if you need to compare another voltage or rating.

We use the nameplate to confirm which table values apply to your unit. These calculations alone do not establish cable size, breaker settings or available fault current. Send existing drawings and test records if available, and have your electrical professional confirm installation requirements for any planned reuse.

Approximate Weight and Oil Volume for a 5 MVA Unit

The weight of a 5000 kVA transformer depends on its voltage class, tank design, windings, cooling equipment and fluid quantity. For preliminary planning, many liquid-filled padmount and substation units fall within an approximate total-weight range of 20,000–45,000 pounds, with roughly 800–2,000 gallons of insulating fluid. Units can fall outside these ranges; check the nameplate and manufacturer’s drawings for the actual weight and fluid quantity.

These estimates are not lift specifications. Confirm whether a listed weight includes fluid, radiators and accessories, and send any separate shipping-weight information. Our transformer weight guide explains why kVA alone is not enough to select lifting equipment.

Tell us whether the tank contains mineral oil, FR3/natural ester or silicone fluid, and report leaks or previous draining. Fluid condition and PCB status affect handling and the purchase review. Use available records or appropriate testing to establish PCB status; confirm current handling requirements before moving or draining equipment.

What Drives Resale Value at 5000 kVA

We evaluate a used 5000 kVA transformer by its electrical configuration, condition and practical reuse potential. A readable nameplate, useful voltage combination and documented operating history give us more information than exterior appearance alone. New surplus equipment should include photos of its crate, storage conditions and any shipping or factory-test documents.

Important factors include:

• Primary and secondary voltages, winding connections, impedance and taps.
• Age, cooling ratings and completeness of radiators, fans and controls.
• Fluid type, PCB documentation, leaks and signs of moisture entry.
• Available electrical tests and the reason it was removed from service.
• Damage to bushings, terminals, tank walls or cable compartments.
• Access and the work required to prepare it for loading.

We also buy failed and scrap units, but we review them differently from serviceable equipment. Tell us about faults, fire exposure or missing parts upfront. Our guide to used transformer value explains how condition and specifications shape an offer.

Send Photos and Records to Sell a 5000 kVA Transformer

To sell a 5000 kVA transformer, call or text 951-403-5738, or submit the details through our transformer offer form. Start with a sharp, straight-on nameplate photo, then include full views of the tank, connection compartments, radiators and any damage. Add the New York pickup location and tell us whether the transformer is disconnected, still installed or stored in a crate.

Include the quantity, condition, fluid type and PCB information. If available, send factory reports or recent results such as winding-resistance, insulation-resistance, turns-ratio and oil tests. We do not require you to energize or test a unit just to submit it for review.

For a failed transformer, describe what happened and what was removed afterward. For stored equipment, note how long it has been idle and how it was protected. We review the information and provide a written offer with the agreed purchase and payment terms.

Pickup Planning for Large Transformers in New York

A 5 MVA transformer needs a loading plan based on its actual weight, dimensions and location. We coordinate rigging, forklift or crane service, and flatbed, step-deck or lowboy trucking as appropriate. If you prefer to load the unit with your own equipment, we can coordinate that arrangement instead.

Send photos showing the route from the transformer to the truck position. Note gates, overhead lines, tight turns, sloped pavement, soft ground and nearby switchgear or cables that restrict access. Tell us about unloading or lifting drawings and any site scheduling restrictions before pickup is booked.

Have qualified personnel isolate and disconnect installed equipment before handling. We do not operate a public New York storefront or drop-off yard; we come to the seller through statewide pickup coordination. Our buying and pickup process includes a quick inspection at pickup to confirm the unit matches the submitted photos, followed by payment by check, ACH or wire under the agreed terms.
