2UEW155 0.18mm Enameled Copper Wire Magnetic Winding Wire For Transformers

Enameled wire 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. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but all have Mechanical properties, chemical properties, electrical properties, thermal properties of four properties.
