Winding Wires

Enamelled Copper Wires are used in the construction of electrical machines such as motors, generators, transformers, house hold appliances, auto-electrical, electrical hand tools, refrigeration (hermetic) motors, fans, switchgears, coils and relays, ballastsand other applications which require tight coils of wire. We manufacture a complete range of wires from 0.08mm to 5 mm in diameter in all nonferrous metals (copper, aluminum, brass, Copper Clad Aluminum etc) with various options of primary insulations ranging from 105⁰C to 220⁰C.

Modern magnet wire typically uses one or more different composition layers of enamel film insulation, providing a tough, continuous insulating layer. Magnet wire insulating films use different applications requiring different qualities use the insulation type such as polyvinyl formal (Formvar), Polyurethane, Polyamide, Polyester, Polyester-Polyimide, Polyamide-Polyimide (or Amide-Imide), and Polyimide. Polyimide insulated magnet wire is capable of operating at up to 250 °C. Completed windings are often vacuum impregnated with an insulating varnish to improve insulation and long-term reliability of the winding.
