This part of GB/T 6109 specifies the requirements for grade 200 enameled copper round wire with a single paint layer based on polyester-amide-imine resin. The resin can be modified if the chemical properties of the original resin are retained 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 usage characteristics. Class 200 represents a thermal class, which requires a minimum temperature index of 200 and a thermal shock temperature of at least 220°C. The Celsius temperature corresponding to the temperature index is not the recommended operating temperature for enameled wire, as this depends on many factors including the type of equipment used. The nominal diameter range of conductors specified in this part is:
——Level 1: 0.018mm and above 1.600mm and below;
——Level 2: 0.025mm and above 5.000mm and below; The nominal diameter of the conductor is according to No. 4 in GB/T 6109.1-2008 regulations of the chapter.
