Enamelled copper wires
Enamelled copper winding wires are designed for manufacturing of stator windings in electric motors, transformers, chokes, electromagnetic relays, oscillating circuit coils, products with maximum thermal and mechanical loads, as well as for windings in electric machinery, automatic equipment and devices, for manual and mechanised winding of wires.
