1070 transformer aluminium strip

At present, the grades of aluminum strips for dry-type transformers mainly include 1060, 1050, 1070, etc. they are mainly used as conductive materials for high and low voltage windings of dry-type transformers. Transformer aluminum strip requires certain tensile strength, elongation and conductivity. The conductivity of 1070 transformer aluminum strip is 62%, the surface is smooth and the edge is free of burrs

1070 transformer aluminum strip starts from the aluminum strip melting and casting process, and strictly controls the melting and casting, rolling, heat treatment, finished product shearing and other process links. By controlling the alloy composition and optimizing the rolling and annealing process, the transformer aluminum strip has achieved high conductivity and mechanical properties.
