Enameled wire, in simple terms, is a layer of insulator, usually plastic, on the outside of the copper wire. The following introduces the meaning of enameled wire, and the difference between enameled wire and copper wire.
First, What is the enameled wire?
Enameled wire is the main variety of winding wires. It consists of a conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.
Second, the classification of enameled wire
- According to the purpose of enameled wire
General-purpose enameled wire (ordinary wire): It is mainly used for winding wires in general motors, electrical appliances, instruments, transformers and other workplaces, such as polyester enameled wire and modified polyester enameled wire.
Heat-resistant enameled wire: Mainly used for winding wires of motors, electrical appliances, instruments, transformers and other workplaces that work in a temperature environment of 180°C and above, such as polyester imide enameled wire, polyimide enameled wire, polyester enameled wire, polyesterimide enameled wire / Polyamide-imide composite enameled wire.
Enameled wire for special purposes: refers to the winding wire with certain quality characteristics required for specific occasions, such as polyurethane enameled wire (straight weldability), and self-adhesive enameled wire.
- The conductor material: are copper wire, aluminum wire, and copper-clad aluminum wire.
- According to the shape of the material: round wire, flat wire, hollow wire.
- According to the insulation thickness
Round line: thin paint film-1, thick paint film-2, thick paint film-3 (national standard).
Flat wire: ordinary paint film-1, thick paint film-2.
Third, the difference between enameled wire and copper wire
Enameled wire is a pure copper wire with a layer of insulating paint on the outside.
General enameled wire: used for windings of transformers, motors and other products.
Pure copper wire is used for: the inner core of the conductor of wire and cable products, and the place where the basic conductor can be used.
