Aluminum Strip for Transformer Winding
As an aluminum strip supplier working with overseas customers, we often receive inquiries for transformer winding materials. For this application, customers usually pay close attention to electrical conductivity, surface cleanliness, edge quality and thickness tolerance. Aluminum strip is widely used in dry-type transformers, oil-immersed transformers, reactors and electrical winding components.

Compared with copper, aluminum strip has lower density and better cost performance. It can help reduce the total weight of the transformer while maintaining stable electrical performance. For many transformer manufacturers, aluminum strip is a practical and economical conductor material.

Requirements
For transformer winding, burr control is very important. Sharp burrs may damage insulation paper or film during winding. Therefore, we recommend customers confirm the edge requirement before placing the order. In addition, the strip surface should be clean, smooth and free from serious scratches, oil stains or oxidation marks.
