The Company also produces several varieties of enameled wire. Enameled wire is copper wire varnished, in an enameling process, by insulating materials. The enameling process makes the wire more resistant to oil, heat, friction and fusion, and therefore suitable for use in machinery and components and sub-components of manufactured goods. The Company manufactures enameled wire in sizes that range from 0.03 mm to 3.00 mm in diameter, varnished by various types of petroleum insulation materials including polyvinyl formal, polyurethane wire and polyester, among others. Enameled wire products are used in the assembly of a wide range of electrical products, including oil-filled transformers, refrigerator motors, telephones, radios, televisions, fan motors, air conditioner compressors and other electric appliances.
Production of enameled wire begins by drawing the copper rods until they have reached the desired diameter, after which the drawn wires are annealed. The annealed wires are then varnished by one or more types of petroleum-based insulation material. Up to seven coats of varnish are applied. Depending upon the intended application of the enameled wire.
