We offer a wide variety of new copper wound transformers both dry and oil built to the industry’s highest standards. We offer .75 KVA to 10 MVA transformers.
Quality Products, Reliable, & High-End Materials.
All Transformers are designed and manufactured to meet or exceed the latest NEMA, ANSI, IEEE and UL STANDARDS. AEC’s Transformer capabilities range up to 10,000 KVA and 69,000 Volts, One or Three Phase, Dry and Oil Types.
CUSTOM MAGNETICS, QUICK DELIVERY, AND SUPERIOR QUALITY IS OUR MAIN BUSINESS. EXPEDITED REPAIR, RETROFIT & PROTOTYPES ARE AVAILABLE.
Transformers undergo a series of tests broken down into three classifications: routine, design and prototype.
These routine tests are made on all DRY TYPE and LIQUID IMMERSED Transformers to insure quality is met:
- Polarity and Phase Relations
- No-load Losses and Excitation Current
- Applied and Induced Potential Dielectric Test
These design tests are made on a sufficient number of Transformers to insure uniform results:
- Impedance Voltage
- Load Losses
- Impulse Dielectric
- Audible Sound level
- Resistance Measurements
- Temperature Rise
These prototype tests are made to insure basic designs
and materials of quality:
- Short-Circuit Capability
- Insulation System
- Weather Classification
NCB guarantees that each Transformer purchased directly is free from defects in material and workmanship, when properly used the product will perform in full accordance with applicable specifications. Any Transformer or component found within Two Years from the date of shipment that does not meet these standards will be reshipped to our facility, at owners expense. The Transformer or Component will be repaired or replaced in a timely manner at no additional charge.
