Scope
This part of GB/T 6109 specifies the requirements for direct-soldering enamelled round copper wires of class 180 with a single paint layer based on polyesterimide resin. The resin can be modified if the chemical properties of the original resin are preserved and all requirements specified for the enameled wire are met. Note: Modified resin is a resin that has undergone chemical changes or contains one or more additives to improve its certain performance or use characteristics. Class 180 indicates a thermal class, which requires a minimum temperature index of 180 and a thermal shock temperature of at least 200°C. The Celsius temperature corresponding to the temperature index is not the recommended temperature for magnet wire use, because it depends on many factors including the type of equipment used. The nominal diameter range of conductors stipulated in this part is: - Class 1: 0.020 mm and above and 1.600 mm and below; - Class 2: 0.020 mm and above and 1.600 mm and below. The nominal diameter of the conductor shall comply with the regulations in Chapter 4 of GB/T 6109.1-2008.
