Dry Type Transformers

Safe, reliable, and maintenance-free power for demanding environments.

Engineered for Safety and Performance

AEC's Dry Type Transformers feature a UL-approved 220°C rated Insulation System, ensuring excellent high-temperature characteristics. Our capabilities extend up to 10,000 KVA with primary voltages as high as 34,500 Volts.


Construction & Technology

Magnetic Cores: Cores are fabricated from precision-cut, burr-free, grain-oriented, high electrical grade silicon steel. These cores are designed for low losses, which reduces operating costs for the user.

Coils: Our precision-made, barrel-wound coils are built using advanced winding equipment with only copper magnet wire as the conductor. We use layered insulation and cooling spacers for improved performance. Each unit undergoes one or two cycles of varnish impregnation and baking to ensure greater electrical strength and a long, reliable service life.
