3750 kVA Transformer Buyers for New York Facilities
We buy individual 3750 kVA transformers and groups of units from contractors, facility managers, utilities, developers and property owners. At this capacity, a transformer may serve a manufacturing plant, a large commercial building, a campus distribution system or a substantial mechanical load. We also review units removed during service upgrades, plant closures and equipment replacement projects throughout our New York service area.
The configuration matters as much as the rating. We review three-phase padmount transformers with enclosed cable compartments and substation transformers arranged with bushings, terminal chambers or connections to adjacent switchgear. Send photos of those connections so we can see what belongs to the transformer and what will remain onsite.
Tell us if the unit is still installed, disconnected, stored outdoors or new in its crate. For multiple units, identify each one separately rather than sending a single rating for the entire lot. Utility-owned transformers belong to the utility and are not for sale by property owners; confirm ownership before requesting an offer.

Voltages, Cooling Ratings and Nameplate Details
Primary voltages encountered at this size include 12,470, 13,200, 13,800 and 34,500 volts. Secondary ratings may include 480Y/277, 600Y/347 or 4,160 volts, depending on the distribution system and connected loads. These are examples, not interchangeable specifications: we need the exact primary and secondary ratings, winding connections and tap range from your nameplate.
A readable nameplate photograph is the best starting point. Include the manufacturer, serial number, manufacturing date, impedance, cooling class, frequency and fluid information. Photograph any separate connection diagram or tap-position label, especially if the unit has multiple voltage configurations.
Check whether 3750 kVA is the base rating or a higher cooling-stage rating. For example, a plate marked 3000/3750 kVA may show different capacities for different cooling conditions. Tell us whether the fans, controls and other cooling components are present and operational. We evaluate the complete rating information rather than treating every unit labeled 3750 kVA as the same specification.
3750 kVA Transformer Full Load Amps
The full-load amps table on this page shows calculated three-phase current at several voltages. At 480 V, a 3750 kVA rating corresponds to 4510.5 A; at 4160 V, it corresponds to 520.4 A; and at 13800 V, it corresponds to 156.9 A. Those values describe different voltage sides or configurations, not three current ratings that apply to every transformer.
For three-phase equipment, the calculation is kVA × 1,000 ÷ (√3 × line-to-line voltage). Our kVA to amps calculator helps compare ratings when you are collecting information for a sale. Use the nameplate voltage and the applicable cooling-stage capacity rather than estimating from the building's service size.
Calculated full-load current is not a measurement of the transformer's present load or a statement of its condition. Send available test reports and operating history separately. These calculations also do not replace engineering decisions about conductors, protection or installation requirements; confirm those details with the qualified professionals responsible for the electrical system.
Approximate Weight, Oil Volume and Pickup Access
For preliminary planning, a liquid-filled 3750 kVA padmount or substation transformer may weigh approximately 15,000–30,000 pounds and contain roughly 600–1,500 gallons of insulating fluid. These are broad estimates, not lifting specifications. Check the nameplate and manufacturer documents for the actual total weight, fluid quantity and handling information; unusual designs can fall outside these ranges.
The weight of a 3750 kVA transformer depends on its tank, core and coils, voltage insulation, cooling equipment and accessories. Dry-type construction requires a separate weight assessment. Our transformer weight guide provides planning context, but we arrange handling around the documented unit weight and site conditions.
Send overall dimensions and photographs showing the route from the transformer to the loading area. Useful details include:
- Whether the unit sits on a pad, rails or a skid.
- Gate widths, overhead obstructions and truck access.
- Available lifting points and their condition.
- Whether a forklift or crane can reach the unit.
- Any stairs, basement access or restricted loading hours.
Include a photo of any existing crate or shipping base, too.
What Drives Resale Value at 3750 kVA
When you sell a 3750 kVA transformer, we review its voltage combination, condition, age, construction and completeness. A used 3750 kVA transformer with a readable nameplate, documented operating history and useful test data gives us more information to evaluate than an unidentified unit. New-in-crate equipment also needs clear specifications and details about storage condition.
Tell us about leaks, damaged bushings, missing fans, corrosion, alarms or a known failure. Available insulation, winding-resistance, ratio and fluid test reports help us review the condition; you do not need to create a new report just to submit the initial inquiry. Our guide to what a used transformer is worth explains the information behind an offer.
Identify the insulating fluid as mineral oil, FR3/natural ester, silicone or another documented type, and send any PCB labels or test results. If PCB status is unknown, say so. Fluid handling and PCB requirements depend on the equipment and current rules; confirm applicable requirements before draining, transporting or disposing of fluid.
We also review failed and scrap units rather than limiting purchases to working equipment.
How We Purchase and Move Your 3750 kVA Transformer
Call or text 951-403-5738, or request a written offer with nameplate photos, condition details and the pickup location. Include whether the transformer is energized, already disconnected or ready to load. We review the specifications, fluid and PCB information, available test data and access before giving you a written offer.
After terms are agreed, we schedule pickup and coordinate the rigging, forklift or crane needed for the unit. Trucking may require a flatbed, step-deck or lowboy, depending on dimensions, weight and loading conditions. If you prefer to load the transformer with your own equipment, tell us so we can coordinate responsibilities and the truck arrangement.
Qualified personnel should de-energize, isolate and disconnect the transformer before handling. At pickup, we perform a quick inspection to confirm that the unit matches the submitted photos and details. Payment is by check, ACH or wire under the agreed terms.
Our buying process covers the steps from submission through pickup. We have no public storefront or drop-off yard in New York; we come to the seller.
Questions sellers ask about 3750 kVA
Who buys used 3750 kVA transformers in New York?
We buy used 3750 kVA transformers anywhere in New York State, including installed units scheduled for removal and equipment already in storage. We also review new surplus, failed and scrap units. Send the nameplate, condition photos, pickup location and confirmation that you own or are authorized to sell the equipment.
What are the full load amps of a 3750 kVA transformer?
For a three-phase 3750 kVA transformer, calculated full-load current is 4510.5 A at 480 V, 520.4 A at 4160 V and 156.9 A at 13800 V. The correct value depends on the winding voltage and applicable capacity rating. Check the nameplate, particularly when it lists more than one cooling-stage rating.
How much does a 3750 kVA transformer weigh?
A liquid-filled padmount or substation unit may weigh approximately 15,000–30,000 pounds, but construction and accessories can put a particular unit outside that range. Check the nameplate and manufacturer documents for the actual weight. We use documented weight, dimensions, lifting information and site access to coordinate pickup equipment.
Can I sell a failed 3750 kVA transformer that still contains oil?
Yes, we review failed liquid-filled transformers, including units that still contain insulating fluid. Tell us what failed, whether there are leaks, the fluid type and any documented PCB status. Do not drain it solely to prepare for an inquiry. We review its condition and handling requirements before agreeing on pickup arrangements.
