For more detailed information including pricing, customization and shipping.
Aluminum foil strip for transformer winding, also called aluminum transformer foil strip, is mainly used for dry type and oil-immersed transformer winding. The thickness of aluminum strip for transformer winding ranges from 0.08mm to 3.00mm and the width ranges from 10mm to 1500mm. Transformer aluminum strip has high conductivity, good corrosion resistance and beautiful appearance, aluminum foil strip for transformer winding is essential in the transformer production process. 1350 O aluminum foil strip, also known as 1350 aluminum foil strip for transformer winding, is a high-purity aluminum alloy with an aluminum content as high as 99.50% or more, has good electrical conductivity, low resistivity, and is easy to process into various shapes and dimensions of conductive material.
