Rectangular copper wire for paper and enamel insulation
In the electrical industry, rectangular wires with defined edge radii are used in motors, generators and transformers.
In comparison with round wires, rectangular wires have the advantage of allowing more compact windings, thereby delivering both space and weight savings. The electrical efficiency is also better, which saves energy.
Especially when the wires are meant to be insulated with enamel, the precision of width and thickness as well as the geometry of the edge radius is of great importance for the defect-free use in electrical coils.
