Custom Engineered Solutions
AEC offers a complete line of liquid-immersed transformers designed to meet rigorous utility and industrial standards. Our capabilities range from 10 to 10,000 KVA, with voltages up to 69,000 Volts. We build single or three-phase units at 60 Hz or 50 Hz for export applications, with standard temperature rises of 55°C or 65°C.
We manufacture all styles of transformers, including pole-mounted, substation, platform, and pad-mounted compartmental units. Our specialty lies in creating custom-built retrofit transformers, providing seamless replacements for aging or unreliable substation equipment. Emergency repairs are also available with industry-leading lead times.
Construction & Materials
Coils: Our precision-made barrel wound coils are built with soft, annealed copper wire and insulated with high-grade materials like Nomex paper or Polyester/Polyamide Imide. The windings are meticulously designed to withstand the mechanical forces of a full short circuit, ensuring longevity and safety. The entire core and coil assembly is oven-dried to remove all humidity before being sealed in its tank and submerged in oil.
Tanks and Compartments: Tanks are fabricated from heavy-gauge, cold-rolled steel and braced to withstand internal pressure of 7 PSI without distortion. We utilize a sealed-tank construction with a resealing pressure relief valve for maximum safety and minimal maintenance. Standard NEMA grounding pads are provided, ensuring secure and proper installation.
