The difference between enameled wire and copper wire is mainly reflected in the material, structure, use and insulation performance.
Material: Copper wire is a conductive material made of pure copper; Enamelled wire is coated with an insulating coating of copper wire.
Structure: Copper wire is usually a single bare copper wire, no insulation layer; The enameled wire is a protective layer of insulating paint outside the copper wire, which can be polyester film, polyurethane, paint and so on.
Usage: Copper wire is mainly used for high-capacity power transmission, such as cables and wires in construction, industry, power and other fields; The enamelled wire is mainly used for winding coils, such as the winding of motors, transformers, etc.
Insulation: The insulating layer of enameled wire can provide good insulation performance, so that the current will not leak or short circuit; The copper wire has no insulating layer, and it needs to be used with insulating materials to ensure safety.
In addition, enamelled wire and copper wire also differ in appearance, physical properties and functions. For example, the surface of the enamelled wire is covered with a layer of enamelled insulation layer, which has various colors and has the characteristics of high temperature resistance, wear resistance, corrosion resistance and insulation performance. The copper wire is a smooth surface, generally yellow or brass, with excellent electrical conductivity.
