150 kVA Transformer Buyers for Dry-Type and Padmount Units
At this rating, we commonly review indoor dry-type transformers and outdoor liquid-filled padmount units. A 150 kVA dry-type transformer may supply lighting, receptacles and smaller equipment loads in a commercial building. A padmount unit may serve a small commercial property or a separate building on a larger site.
In New York, sellers may have units available after a tenant renovation, warehouse electrical upgrade, manufacturing-line change or redevelopment project. We also buy unused contractor stock and spare transformers that no longer match a facility's distribution system. Tell us why the unit is available and whether it remains connected or has already been removed.
For an indoor unit, our dry-type transformer buying information explains the details we review. For an outdoor cabinet, see our padmount transformer buying information. Confirm ownership before offering equipment: utility-owned transformers belong to the utility and cannot be sold by the property owner.

Common Voltages and 150 kVA Transformer Full Load Amps
A common three-phase dry-type configuration is a 480 V primary with a 208Y/120 V secondary. Other units have a 600 V primary or different secondary voltages. At 150 kVA, padmount transformers may have medium-voltage primaries such as 12,470 V, 13,200 V or 13,800 V, paired with secondaries such as 208Y/120 V or 480Y/277 V. We need the actual nameplate rather than a voltage guessed from the building service.
The template's 150 kVA transformer full load amps table shows calculated three-phase current at several voltages. At 208 V, the value is 416.4 A; at 480 V, it is 180.4 A; and at 12,470 V, it is 6.9 A. These use line-to-line voltage and the three-phase formula, not the single-phase formula.
Our kVA-to-amps calculator helps explain that relationship. Send the phase, winding connections and tap information with the voltage ratings. Calculated full-load current alone is not enough to select conductors, protection or installation equipment.
Approximate Weight and Oil Volume for Pickup Planning
The weight of a 150 kVA transformer depends on its construction, winding material, enclosure and accessories. For preliminary planning, a three-phase dry-type unit may weigh approximately 800–2,000 pounds. A liquid-filled padmount unit may weigh approximately 1,500–3,500 pounds. These are broad planning ranges, not lifting specifications; check the nameplate for the actual weight.
A 150 kVA liquid-filled padmount transformer may contain approximately 80–160 gallons of insulating fluid, depending on its design. Check the nameplate for fluid type and volume, and use manufacturer documentation if those details are missing. Dry-type transformers do not contain insulating oil.
Our transformer weight guide provides additional planning context, but we arrange handling around the specific unit. Send photos of its base, lifting provisions and any attached equipment, along with known leaks. Keep fluid contained and have qualified personnel handle disconnection; confirm current PCB, transport and disposal requirements when applicable. Tell us about any fluid sampling or PCB documentation before we schedule pickup.
What Drives Resale Value at 150 kVA
We evaluate a used 150 kVA transformer by its electrical configuration, condition and the information available to support resale. A readable nameplate, intact enclosure and documented operating history give us a clearer basis for an offer. Common voltage combinations may be easier to match to another application than unusual configurations.
New-in-crate equipment should include photos of the crate, labels and transformer nameplate if accessible. For used equipment, tell us when it last operated, why it was removed and how it has been stored. Existing test reports help us review condition; there is no need to describe an untested unit as tested.
Failed or damaged units need a different review. We consider winding material when known, physical damage, fluid status and recovery options rather than treating them as ready-to-install equipment. Access and loading requirements also affect the offer. Our guide to what a used transformer is worth explains the broader factors, but we quote from your unit's details rather than from kVA alone.
Photos and Details We Need for a Written Offer
Start with a sharp, straight-on nameplate photo and several pictures showing the complete transformer. For a padmount, include the exterior cabinet and base; photograph compartment interiors only when safely accessible to qualified personnel. For a dry-type unit, show the enclosure, ventilation openings and any visible damage.
Include these details with your photos:
- Quantity, manufacturer and model or serial number.
- Primary and secondary voltages, phase and kVA rating.
- Approximate age, operating history and present condition.
- Fluid type and PCB information for liquid-filled equipment.
- Available test reports, manuals or purchase records.
- Pickup town, current placement and available loading equipment.
Use our online transformer offer form to submit the information. If your project includes different ratings, identify each unit separately; our 225 kVA transformer buying page covers that nearby size. Clear labels help us keep photos, ratings and quantities matched when we prepare a written offer for multiple transformers.
How We Pick Up 150 kVA Transformers Across New York
We coordinate pickup at the seller's location throughout our New York service area. We have no public storefront or drop-off yard in New York. Call or text 951-403-5738 with your photos and location so we can review the unit and the handling needed.
For a dry-type transformer, tell us if it is on a pallet, bolted to a floor or located inside a building. Door width, stairs, freight-elevator limits and the route to the loading area matter. For a padmount, describe truck access, overhead clearance, ground conditions and the equipment available to lift it from the pad.
After agreeing on an offer, we schedule pickup and coordinate rigging, a forklift or crane, and suitable trucking. You may load the transformer if you prefer, under the agreed arrangement. We perform a quick pickup inspection to confirm it matches the photos, then pay by check, ACH or wire under the agreed terms. Our buying and pickup process explains the sequence.
Questions sellers ask about 150 kVA
Where can I sell a used 150 kVA transformer in New York?
We buy used 150 kVA transformers anywhere in New York State and coordinate pickup at your location. Send nameplate photos, overall photos, condition details and your town. We review the unit and provide a written offer. We do not have a public New York drop-off yard.
How many amps is a 150 kVA transformer at 480 volts?
For a three-phase 150 kVA transformer at 480 V line-to-line, calculated full-load current is 180.4 A. Single-phase current uses a different formula. We ask for the nameplate to confirm phase and both winding voltages, since the primary and secondary currents differ according to their voltage ratings.
How much does a 150 kVA transformer weigh?
For preliminary planning, a three-phase dry-type unit may weigh approximately 800–2,000 pounds, while a liquid-filled padmount may weigh approximately 1,500–3,500 pounds. Construction and accessories affect weight. Check the nameplate and manufacturer documentation for the specific unit; we need its actual weight before selecting lifting and loading equipment.
Do you buy failed or leaking 150 kVA transformers?
We review failed, damaged and scrap 150 kVA transformers as well as working units. Tell us what failed, show any damage or leaks, and provide fluid and PCB documentation if available. We need those details to evaluate recovery options and pickup requirements. Keep leaking fluid contained while arrangements are reviewed.
