20 MVA Transformer Buyers for New York Power Equipment
A 20 MVA transformer is rated at 20,000 kVA. At this size, we primarily evaluate three-phase, oil-filled substation and power transformers rather than the smaller distribution units commonly installed beside individual buildings. Send the complete nameplate so we can see whether 20 MVA is the base rating or a higher rating that depends on fans or other cooling equipment.
These units can serve utility substations, large industrial facilities, major campuses and generating facilities. In New York, a seller may have equipment available after a plant shutdown, substation replacement, redevelopment project or solar and battery-storage project change. Step-up units require particular attention to their voltage ratio and connection arrangement.
Our substation transformer buying page covers that equipment category, and our New York service area covers statewide pickup coordination. We buy seller-owned equipment; a utility-owned transformer on your property belongs to the utility and is not yours to sell. Confirm ownership before requesting an offer.

Common Voltages and 20 MVA Transformer Full Load Amps
Voltage combinations depend on the installation. Examples at this scale include 69 kV or 115 kV on the high-voltage side with 13.8 kV or 34.5 kV on the low-voltage side. A substation application may instead use 34.5 kV to supply a 12.47 kV or 13.2 kV system. These are examples, not a specification for every 20 MVA unit.
The template's 20 MVA transformer full load amps table shows calculated three-phase current at several voltages. At 13,800 V, the listed current is 836.7 A; at 34,500 V, it is 334.7 A; and at 4,160 V, it is 2775.7 A. These values use the full 20,000 kVA rating, not the transformer's measured operating load.
Use our kVA to amps calculator to check a particular winding voltage. For our review, send both winding voltages, connection details, impedance, tap range and every cooling-stage rating. Our transformer sizes reference helps distinguish the kVA rating from voltage and current when organizing an equipment list.
Approximate Weight and Oil Volume for a 20 MVA Unit
For rough planning, the weight of a 20 MVA transformer may fall around 70,000–160,000 pounds with fluid and installed equipment. Oil volume may be approximately 3,000–8,000 US gallons. Designs vary substantially with voltage class, cooling arrangement and construction, so check the nameplate and manufacturer's documentation rather than using these ranges to book a crane or truck.
Total operating weight is not always the shipping weight. Radiators, a conservator, bushings or other components may have separate shipping arrangements, and any proposed disassembly needs a qualified plan. Send drawings or shipping records if you have them, along with dimensions and photographs showing the complete installed unit.
Our transformer weight guidance explains why kVA alone cannot establish lifting weight. For pickup planning, we also need to know the fluid type, whether the tank is full or drained, and whether any detached components remain on site. Do not drain fluid or remove components just to prepare a quote; first establish the agreed scope and handling requirements.
What Drives the Resale Value of a Used 20 MVA Transformer
When you sell a 20 MVA transformer, the rating is only one part of the evaluation. We consider how its specifications fit another installation, what documentation supports its condition, and what it will take to remove and transport it. A usable transformer and a failed unit need different assessments, even when their nameplates show the same capacity.
The most useful details include:
- Manufacturer, serial number, year and complete cooling ratings.
- Primary and secondary voltages, winding connections, impedance and tap-changer details.
- Available electrical test reports, oil analysis and maintenance records.
- Known faults, leaks, bushing damage, missing parts or storage issues.
- Fluid type, PCB documentation and the removal site's access limitations.
Our guide to what a used transformer is worth explains the broader evaluation factors. For a used 20 MVA transformer, tell us when it last operated and why it was removed. We also review new surplus, damaged and scrap units, so describe the condition plainly rather than trying to make a failed transformer sound serviceable.
How We Coordinate Pickup for a 20 MVA Transformer
We come to the seller; we do not operate a public storefront or drop-off yard in New York. For a transformer this size, pickup planning starts with confirmed weight, dimensions, lifting information and site access. Photos should show the approach route, loading area, overhead obstructions and the unit's position relative to fences, walls and adjacent switchgear.
We coordinate suitable rigging and crane or forklift resources, together with flatbed, step-deck or lowboy trucking as appropriate to the load. Trailer selection depends on actual shipping dimensions and weight, not simply the 20 MVA rating. If you prefer to load the unit, tell us what equipment and loading arrangements you have available.
Our buying and pickup process includes a quick inspection at pickup to confirm that the equipment matches the photos and agreed description. Identify any disconnection, dismantling or access work still required before scheduling. Electrical isolation and removal work must be handled by qualified personnel. We agree on the loading scope and payment terms before pickup, with payment by check, ACH or wire under those terms.
Send Nameplates, Fluid Records and Site Photos for an Offer
Call or text 951-403-5738, or use our transformer offer form. Start with a readable photo of the full nameplate, overall views of the transformer, and the town or ZIP code where it is located. Include your contact information, ownership status, whether the unit is still connected, and any deadline affecting removal.
For a large oil-filled unit, add fluid and PCB records, test reports if available, and photos of the bushings, radiators, tap changer and visible damage. If the nameplate lists several MVA ratings, photograph all of them. Let us know whether control cabinets, fans and detached accessories are included in the sale.
If PCB status is unknown, say so rather than guessing from the transformer's age or appearance. Fluid handling and transportation requirements depend on the equipment and documented fluid status; confirm current requirements with qualified environmental and transportation professionals. We review the information, clarify missing details and provide a written offer covering the equipment and agreed pickup scope.
Questions sellers ask about 20 MVA
Who buys a used 20 MVA transformer in New York?
We buy used 20 MVA transformers anywhere in New York State, along with new surplus, decommissioned, damaged and scrap units. Send the complete nameplate, condition details, location and site photos. We review the specifications and removal requirements, provide a written offer, and coordinate pickup under the agreed terms.
What are the full load amps of a 20 MVA transformer?
For a three-phase transformer, full-load current depends on the winding voltage. At 13,800 V, a 20 MVA rating corresponds to 836.7 A; at 34,500 V, it corresponds to 334.7 A. Use the table for the applicable voltage, and check the nameplate for the winding voltage and cooling-stage rating that apply to your unit.
How much does a 20 MVA transformer weigh?
A rough planning range is approximately 70,000–160,000 pounds with fluid and installed equipment, but individual designs can fall outside that range. Check the nameplate and manufacturer's drawings for actual operating and shipping weights. We also need dimensions and the planned shipping configuration before coordinating rigging and transportation.
Can I sell a failed 20 MVA transformer with oil still inside?
We review failed and damaged oil-filled transformers, including units that still contain fluid. Tell us the failure history, fluid type, known leaks and documented PCB status. Do not drain the tank solely to request an offer. Fluid condition, handling requirements and site access must be reviewed before we agree on the pickup plan.
