Aluminum Strip For Transformer

Aluminium strip is used as a conductor in dry-type transformers to wound on the core instead of copper winding. Aluminium strip for transformer wingding is required with high conductivity, soft, smooth surface, no burr and high quality. In general, the aluminum strips alloys used in dry type transformers are 1050, 1060 and 1070 with temper O which is soft. The thickness is 0.08-3.0mm and the width is 30-1500mm.

aluminum strip

1060 transformer aluminum strip of O temper with high aluminum content, and the conductivity and thermal conductivity is only lower than the conventional copper metal. As the price of copper is much higher than aluminum, so the most commonly used material for the transformer is aluminum strip. Transformer aluminum grades are mainly 1060-O, mainly used in dry-type transformers, high and low voltage winding used as conductive material. Transformer aluminum strip is mainly used for large transformers, solar energy, power industry. 1060 aluminum alloy becomes the important material in transformer aluminum strip. The advantages of this series are the most commonly used series, the production process is relatively simple, relatively mature technology, the price has a huge advantage relative to other high-grade aluminum alloy. 1060 transformer aluminum strip has good elongation and tensile strength, fully able to meet the conventional processing requirements (stamping, stretching), high molding ability for industrial pure aluminum, with high plasticity, corrosion resistance, conductivity and thermal conductivity, but the strength is low, heat treatment can not strengthen it. The machinability is not good.
