0.02 - 1.8mm rectangular / flat enamelled copper wire

In the electrical industry, rectangular wires with defined corner 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.
