In dry type transformers, aluminum winding have been commonly used. Aluminum strip can replace copper conductor in distribution transformers. Aluminum foil and sheet in appropriate strip widths and lengths have widely replaced wire in electrical transformers. Demand for aluminum strip/foil using for oil transformer is new and will be more.

Haomei produce high conductivity roll type electrolytic aluminum foil used to manufacture the winding of electrical transformer, distribution transformer and cast resin transformer.
