1050/1060 Aluminum Strip for Transformer Winding

 Why We Use Aluminum Strip for Transformer

The electrical and thermal conductivity of aluminum is only lower than copper. Since the price of copper is much higher than that of aluminum, the most commonly used material for transformer is aluminum strip/foil/sheet.

Characteristics of 1060 Aluminum Strip for Transformer

1060(O) Aluminum strip is mainly used as high- and low-voltage winding for dry-type transformers. It has high conductivity, soft texture, smooth surface and no burr. It is an ideal material for the production of dry-type transformers and a key raw material for the manufacture of transformer winding.
