Round Edge Aluminum Strip for Transformer

Round edge aluminum strip for transformer is widely used in transformer winding systems where smooth edges, reliable conductivity and stable dimensional accuracy are required. Compared with conventional slit aluminum strip, the round edge design helps reduce the risk of insulation damage during winding and improves the safety and reliability of transformer production.

Our transformer aluminum strip can be supplied in different alloys, tempers, thicknesses and widths according to customer requirements. With precise slitting, edge treatment and strict quality inspection, the material is suitable for dry-type transformers, oil-immersed transformers, distribution transformers and power transformers.
