Mining Transformers


Acutran designs and manufactures field-proven, low-profile mining duty transformers for a variety of mining environments and applications.

Mining duty transformers are used extensively at mines, converting and distributing voltage utilized for distribution, load center, and shovel duty. They must have high power, a low profile, and a compact design to be suitable for rugged mining locations.

Reliability and performance are critical for mining transformers, and control systems are becoming increasingly complex. That’s why major mining companies and mine service providers in North America trust the experts at Acutran for robust, rugged solutions for their power centers and power distribution systems.


Acutran dry-type mining transformers are custom engineered and manufactured for harsh mining environments, including:

Underground Mining

Surface Mining

Process Plants
