Transformers are designed and built with copper or aluminum winding. But transformers using aluminum coil winding have advantage of small size, light weight, good insulation properties, flame retardant, non-polluting, partial discharge, resistant to moisture, smooth and reliable operation, low noise, and low maintenance cost.


In dry type transformers, aluminum–aluminum winding have been commonly used. Aluminum strip can replace copper conductor in distribution transformers. Aluminum coil and sheet in appropriate strip widths and lengths have widely replaced wire in electrical transformers.


Demand for aluminum coil using for oil transformer is new and will be more.
