Power‑grid engineers, procurement managers, and operations leaders in the USA get exact 15 MVA transformer specs that cut cost by up to 30 % while meeting UL, IEC, and RoHS standards.
You’ve likely faced one or more of these setbacks:
According to a 2025 industry survey, 62 % of US utilities reported at least one transformer‑related delay in the past two years, averaging a $1.2 M loss per incident.
| Parameter | Standard Value | Unit | Notes |
|---|---|---|---|
| Rated Power | 15 | MVA | Continuous |
| Primary Voltage | 13.8 | kV | Typical – customizable |
| Secondary Voltage | 0.4 | kV | Standard industrial |
| Frequency | 50/60 | Hz | Dual‑frequency option |
| Efficiency (at 75 % load) | ≥ 98.5 | % | IEC 60076‑3 |
| Impedance Voltage | 5.5 | % | Adjustable via tap changer |
| Cooling Method | Oil‑immersed, natural circulation | — | Optional forced‑oil |
| Temperature Rise | ≤ 55 | °C | At rated load |
| Noise Level | ≤ 55 | dB(A) | Measured at 1 m |
| Weight | ≈ 12,800 | kg | Depends on core material |
| Warranty | 24 | Months | Full parts & labor |
Utility Substations (USA – Texas): Replaced a legacy 12 MVA unit with our 15 MVA custom design, achieving a 28 % reduction in line losses and a 3‑week project acceleration.
Industrial Manufacturing (Midwest Steel Plant): Integrated a dual‑frequency 15 MVA transformer for a new furnace line, meeting ISO 50001 energy‑management goals and cutting electricity cost by $420 K per year.
Data Center Power Distribution (California): Delivered a low‑noise, high‑efficiency transformer that kept acoustic levels below 55 dB, complying with local building codes.
Standard stock is ready within 7 days. Custom OEM/ODM designs require 2‑3 weeks of engineering plus 1‑2 weeks of production, then 2 weeks for air freight.
Yes. Our R&D team can increase the short‑circuit withstand rating up to 30 kA by selecting a thicker core and reinforced windings. Lead‑time may extend by 5‑7 days.
We accept T/T (30 % TT in advance, 70 % before shipment), L/C at sight, and PayPal for sample orders. All prices are quoted in USD.
Every unit undergoes third‑party UL testing, and we provide the full test report, CE mark, and RoHS declaration. For FCC‑related emissions, we supply the necessary shielding options.
A 24‑month warranty covers parts, labor, and on‑site troubleshooting. We also offer a 5‑year extended service contract with annual performance checks.
Limited‑time offer: Free engineering sample (up to 5 kVA) and a money‑back guarantee if the transformer does not meet the agreed specifications.
