The raw material of transformer aluminum coil strip is pure aluminum cast-rolled aluminum coil or hot-rolled aluminum coil, which is rolled into a thin aluminum coil of different thickness and width by a cold rolling machine, and then longitudinally slit into different widths by slitting machine according to the purpose During the slitting process, the edge burrs are removed or rounded to avoid the penetration of insulating paper in the later period.


The alloy grades of commonly used aluminum strips are 1050, 1060, 1070, 1350, and 1370. Commonly used states are O state and soft state.

The transformer aluminum coil strip is divided into a high-voltage transformer band and a low-voltage transformer band. The high-voltage band is narrower and thinner, and the low-voltage band is wider and thicker.
