750 kVA Transformer Buyers for Facility and Site Upgrades
We buy 750 kVA transformers from contractors, facility managers, developers and owners who have equipment they own and are authorized to sell. At this rating, we commonly review three-phase units supplying commercial buildings, manufacturing facilities, warehouses and larger residential properties. In New York, a sale may follow a service upgrade, redevelopment, plant closure or replacement of aging equipment.
Outdoor 750 kVA padmount transformers usually have enclosed cable compartments and sit on a concrete pad. They may have dead-front or live-front connections, with loop-feed or radial-feed arrangements. Clear compartment photos help us identify the configuration and see whether bushings, connectors and accessories remain intact.
We also review substation and unit-substation transformers, including units installed beside switchgear or inside electrical rooms. Indoor dry-type transformers at this size need a different handling plan from liquid-filled equipment. Tell us whether the unit is freestanding, attached to adjacent equipment or still connected. Utility-owned transformers belong to the utility and are not available for a property owner to sell.

Common Voltages and 750 kVA Transformer Full Load Amps
A 750 kVA rating alone does not tell us whether a transformer suits another installation. We need both primary and secondary voltages, phase, frequency, winding connection and available taps. Common medium-voltage primary ratings include 12,470, 13,200 and 13,800 volts; we also review units with other ratings, including 4,160 or 34,500 volts. Common low-voltage secondaries include 480Y/277 and 208Y/120 volts, with 600-volt units also appearing in industrial applications.
The full-load amps table on this page shows calculated three-phase current at each listed line-to-line voltage. For a 750 kVA transformer, the values include 2081.8 A at 208 V, 902.1 A at 480 V and 34.7 A at 12470 V. These are calculated rating values, not measured operating loads or a substitute for equipment-specific information.
Our kVA-to-amps calculator explains the relationship between capacity, voltage and current. Send a readable nameplate rather than identifying the transformer only as “750 kVA, 480 volts.” The primary rating, connection diagram and tap information matter when we evaluate resale suitability.
Approximate Weight and Oil Volume for Pickup Planning
The weight of a 750 kVA transformer varies with its design, enclosure, conductor material and fluid. For initial planning, many liquid-filled padmount and substation units fall within an approximate range of 5,000–12,000 pounds, with roughly 200–400 gallons of insulating fluid. These are broad estimates, not lifting specifications; check the nameplate and manufacturer documentation for the actual unit.
Dry-type construction has different weight and clearance requirements, so we do not use an oil-filled estimate to select handling equipment for a dry-type unit. Our transformer weight guide provides general planning context, but we need the actual weight before finalizing a lift. If the nameplate weight is missing or unreadable, tell us rather than guessing.
Send photos of lifting points, the base, radiators and any attached compartments. Include overall dimensions and indicate whether the listed weight includes fluid. Tell us if oil has been drained, if the tank leaks or if accessories have been removed; those details affect both the offer and transport preparation.
What Drives Resale Value at the 750 kVA Rating
We assess a used 750 kVA transformer by its electrical configuration, condition, completeness and available documentation. A usable voltage combination and intact connections help us evaluate the unit for reuse. New surplus equipment should be documented with nameplate and crate photos, along with any storage history you have. For used equipment, tell us why it was removed and whether it operated normally before shutdown.
The details that most directly inform our review include:
- Primary and secondary voltages, winding connection, taps and impedance.
- Manufacturer, age and whether the nameplate remains legible.
- Mineral oil, FR3/natural ester, silicone or dry-type construction.
- Available electrical test reports, fluid results and PCB information.
- Condition of bushings, radiators, enclosure, terminals and accessories.
- Pickup access, loading requirements and the number of units offered.
We also buy failed and scrap transformers. Describe overheating, internal faults, flood exposure, leaks or missing parts clearly so we can assess the correct disposition. Our guide to what a used transformer is worth explains the broader evaluation factors. At 750 kVA, we review the complete unit and removal requirements rather than treating every transformer of the same rating as equivalent.
What to Send When You Sell a 750 kVA Transformer
Call or text 951-403-5738, or use our transformer offer form. Start with a close, readable nameplate photo and several full-unit photos. Include your name, the New York pickup location, the number of transformers and whether each unit is installed, disconnected, stored outdoors or still in its original crate.
For a 750 kVA padmount, photograph the enclosure, base and accessible connection compartments. For a substation unit, show the tank or coils, radiators, terminal arrangements and its relationship to adjacent switchgear. Only have qualified personnel access electrical compartments; do not open energized equipment for sales photos.
Send test records and fluid or PCB documentation if available, and state when that information is unknown. PCB identification and handling can affect the removal plan; confirm current applicable requirements with qualified environmental personnel. Also tell us about stairs, doorway restrictions, fencing or limited truck access. We use these details to prepare a written offer and establish practical pickup terms before scheduling.
How We Coordinate Pickup of a 750 kVA Unit
We coordinate pickup throughout our New York service area, including sites where the transformer is behind a building, inside a plant or in an equipment yard. We have no public storefront or drop-off yard in New York; we come to the seller. Before scheduling, we confirm the unit’s location, dimensions, weight, loading access and the work needed to make it ready for removal.
A forklift may suit a properly accessible unit when its capacity and load-center rating are adequate. Other sites require a crane or specialized rigging, particularly when equipment must clear a fence, leave an electrical room or be lifted from a restricted pad. We coordinate rigging and flatbed, step-deck or lowboy trucking as appropriate, or you can load with your own suitable equipment under the agreed plan.
Our buying and pickup process includes a quick inspection at pickup to confirm the transformer matches the photos and description. Tell us in advance if disconnection, draining or site restoration remains unfinished so responsibilities are clear. Payment is by check, ACH or wire under the agreed terms. For multiple 750 kVA units, identify each nameplate separately so the offer and loading plan match the equipment being sold.
Questions sellers ask about 750 kVA
Who buys used 750 kVA transformers in New York?
We buy used 750 kVA transformers anywhere in New York State, including padmount, substation and dry-type units. We also review new surplus, failed and scrap equipment. Send nameplate photos, condition details and the pickup location so we can evaluate the unit and provide a written offer.
How many amps does a 750 kVA transformer supply at 480 volts?
For a three-phase 750 kVA transformer at 480 volts line-to-line, calculated full-load current is 902.1 A. Actual operating current depends on the connected load. We use the nameplate voltage and phase information when reviewing a unit; the calculated value alone does not establish conductor sizing, protective-device settings or installation requirements.
How much does a 750 kVA transformer weigh?
Many liquid-filled 750 kVA transformers weigh approximately 5,000–12,000 pounds, but construction and accessories can put a particular unit outside that range. Check the nameplate and manufacturer documentation. We need the actual weight, dimensions and access details to coordinate suitable lifting equipment and trucking; a general estimate is not a lift specification.
Can I sell a failed 750 kVA transformer with oil still inside?
We review failed liquid-filled 750 kVA transformers, including units with fluid still inside. Tell us the fluid type, known PCB status, failure history and whether the tank leaks. Do not drain it solely for a sale without discussing the removal plan. We assess condition and documentation before agreeing on handling and pickup terms.
