Enamelled Copper Wire
Enamelled Copper Wire or Enamelled Aluminum Wire is used in the construction of transformers, inductors, motors, headphones,loudspeakers, hard drive head positionable, potentiometers, and electromagnets, and many more applications. Enameled wire is covered with thin insulation. Enameled copper wire typically uses one to three layers of polymer film insulation, to provide a tough, continuous insulating layer.
