The thermal grade of enameled wire is divided into 130 grades, 155 grades, 180 grades/200 grades, and the thermal grade is the temperature resistance grade, which can withstand temperatures of 130°, 155°, 180°/200°, according to different use environments To choose the enameled wire suitable for the thermal class. The high temperature is 200°, and 130° is commonly used.
Enameled wire to refers to the metal wire used to wind the electromagnetic coil of insulating varnish as the insulating coating, also called electromagnetic wire. It is one of the main types of winding to wire, which consists of a conductor and an 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 not only meet standard requirements but also meet customer requirements. It is affected by factors such as the quality of raw materials, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all It has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.
