Enameled copper wires are often called enameled wires because these wires are coated with an insulating layer. Enameled copper wire is widely used in the manufacture of motors, inductors, hard disk head actuators, and various applications that require tightly wound insulated wires. When used in machines such as transformers and motors, both aluminum and copper wires can be painted.

Enameled copper wire is usually thicker than enameled aluminum wire, and its thickness is compensated by an additional insulating layer. Since the conductor of the wire is a straight coil, and because its insulation layer is particularly thick, it cannot conduct current through the wire. The thicker insulating layer also helps shield the arc, and it also acts as a conductor, thereby reducing the possibility of arcs entering the coil. This insulation method does not allow any moisture to enter the wire, and uses special non-corrosive materials, so that this type of wire has a longer service life. For this reason, it is generally superior to aluminum or copper wires, which may corrode over time because of the accumulation of moisture on the surface.

The reason for using enameled copper wire is to prevent the surface of the wire from being short-circuited when it is wound into a coil. This explains why it is often used to make electromagnets, inductors, transformers and motors. Wires can also be soldered to make the manufacturing of inductive components easier. When the enameled wire is wound to form a coil, an electromagnetic field is generated, and then it is re-energized.

Be careful when using this wire, because once the wire is exposed to electricity, it will easily overheat, which is very harmful to the wire. Therefore, you need to place the wires in an enclosed area away from any water or humidity.
