Dry Type Distribution Transformers

Dry Type Distribution Transformers.
Step Up or Step Down.


SolaHD offers several Hevi-Duty™ distribution transformers which meet the Department of Energy’s (DOE) Code of Federal Regulations, title 10, part 431 (also known as DOE 10 CFR p431, or DOE 2016). Our general purpose distribution transformers are available in open core and coil, copper wound, and totally enclosed, non-ventilated designs. We provide single and three phase indoor and outdoor models from 15 kVA through 500 kVA. Low temperature rise models and specialized K-Factor transformers are designed to withstand the harmonic currents of non-linear loads without experiencing voltage instability or overheating.

In addition to the DOE 2016 transformers, we offer encapsulated, non-ventilated automation transformers and Ex e certified TRE Series transformers. Both series are ideal for use in hazardous and harsh industrial environments.

If you cannot find the exact transformer you need among our extensive selection, contact your local SolaHD sales representative about building a custom transformer to fit your needs.​

SolaHD dry type, step down, ventilated, low temperature rise transformers are designed for any critical application requiring extra overload capability, lower than average total losses and-or cooler operating temperatures
SolaHD's dry type, step down K-Factor transformers are designed to reduce the heating effects of harmonic currents created by loads without exceeding the temperature rating of the insulation system
SolaHD step up or step down general purpose transformers are 600 Volt Class transformers that feature dry type construction and are classified as isolation transformers
SolaHD’s non-ventilated automation transformers are used in hazardous and harsh industrial environments. Encapsulation and rugged NEMA 3R enclosure protect the transformer from dust and moisture while providing extra shock and vibration resistance
Appleton's ATX TRE Series Ex e Transformers are equipment transformers for changing the available line voltage, 230-400 V or 240-415 V, to accommodate the required load and safety voltage
