[Electrical equipment knowledge] Types and standards of enameled wires

Enameled wire is also called winding wire. It is a wire with an insulating paint layer coated on the conductor. It is mainly used to convert electromagnetic energy in electrical equipment and is one of the main components of transformers. The structure of enameled wire has two parts: conductor and insulation. Depending on the shape, conductor and insulation, enameled wire has different divisions.
