Enameled aluminum wire refers to a aluminum wire that uses insulating varnish as an insulating coating and is used to wind an electromagnetic coil, also known as an electromagnetic wire. It is a main variety of winding wire. It consists of conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. In most cases, enameled wire is wound into coils of different shapes to provide electromagnetic fields for motors, transformers, electromagnets and other products.
According to the shape classification, LP Industry enameled aluminum wire mainly produces enameled round wire and enameled flat wire.
