GB/T 23312.6-2009
Scope
This part of GB/T 23312 specifies the requirements for double-coated 180-grade enamelled round aluminum wire. The primer layer is based on polyester or polyester sub-acrylic resin, which can be modified if the chemical characteristics of the original resin are preserved and all requirements specified for enameled wire are met. The topcoat layer is based on polyamide resin. Grade 180 indicates a thermal grade, requiring 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 specified in this part is: ——Class 1: 0.250mm and above and 3.150mm and below; ——Class 2: 0.400mm and above and 5.000mm and below. See GB/T 23312.1-2009 for the nominal diameter of conductors Chapter 4.
