Scope
This part of GB/T 6109 specifies the requirements for double-coated 130-grade enamelled round copper wire for direct soldering. The primer layer is based on polyurethane 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. The topcoat layer is based on polyamide resin. 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 130 indicates a thermal class, which requires a minimum temperature index of 130 and a thermal shock temperature of at least 155°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 specified in this part is: - Class 1: 0.050 mm and above and 1.600 mm and below; - Class 2: 0.050 mm and above and 2.000 mm and below. The nominal diameter of the conductor shall comply with the regulations in Chapter 4 of GB/T 6109.1-2008.
