- Scope
- This part of GB/T 6109 specifies the requirements for double-coated 200-grade enamelled round copper wire. The primer layer is based on polyester or polyesterimide resin, which 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 polyamideimide 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 200 indicates 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 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: 0.050mm and above and 2.000mm and below; —Class 2: 0.050mm and above and 5.000mm and below. The nominal diameter of the conductor shall comply with the regulations in Chapter 4 of GB/T 6109.1-2008.
