This part of GB/T 6109 specifies the requirements for grade 120 enameled copper round wire with a single paint layer based on polyvinyl acetal 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 120 represents a special grade, which requires a minimum temperature index of 120 and a thermal shock temperature of at least 155°C. The Celsius temperature corresponding to the temperature index is not the recommended temperature for enameled wire because it depends on many factors including the type of equipment used. . The nominal diameter range of conductors specified in this part is:
——Grade 1: 0.040 mm and above and 2.500 mm and below;
——Grade 2: 0.040 mm and above and 5.000 mm and below;
——Grade 3: 0.080 mm and above and 5.000 mm and below. The nominal diameter of the conductor is in accordance with Chapter 4 of GB/T 6109.1-2008.
