Aluminium strip for transformer in Haomei

Aluminium strip is used as a conductor in dry-type transformers to wound on the core instead of copper winding. Aluminium strip for transformer winding is required with high conductivity, soft, smooth surface, no burr and high quality. According to the analysis, the chemical composition, hot rolling, cold rolling, shearing, heat treatment processes, internal organization, electrical conductivity, hardness and mechanical properties of materials will affect the application on transformer winding. In common, the aluminum strips alloys used in dry type transformers are 1050, 1060, 1070 and 1350, the temper is O which means soft, the thichness is 0.08-3.0mm and the width is 16-1500mm.

When the aluminium strip is wound on the transformer core, the aluminum strip is tensioned to maintain a certain tension, and the transformer winding coil is wound smoothly and flatly. So the temper soft is usually used in the aluminum strips for transformer winding. To improve the quality of produced aluminium strips, the high-precision aluminum coil slitting unit is adopt, independent research and development of edge chamfering technology for high-precision round edge fillet processing.Thus, the aluminium strip for transformer produced by Haomei Aluminum is with round edge and without burr, which meet the requirements and welcomed by our customers, they are willing to have long term cooperation with our factory, and the monthly output of aluminum strips is up to 1000 tons in Haomei.
