GB/T 23312.2-2009 in English

《GB/T 23312.2-2009漆包铝圆绕组线 第2部分：120级缩醛漆包铝圆线》由TC213（全国电线电缆标准化技术委员会）归口，TC213SC1（全国电线电缆标准化技术委员会绕组线分会）执行，主管部门为中国电器工业协会。
GB/T 23312的本部分规定了以聚乙烯醇缩醛树脂为基的单一漆层１２０ 级漆包铝圆线的一般要求。如能保留原树脂的化学特性并满足对漆包线规定的所有要求，则该树脂可以改性。

Scope

This part of GB/T 23312 specifies the general requirements for grade 120 enamelled round aluminum wire with a single paint layer based on polyvinyl acetal resin. Resins may be modified if the chemical properties of the original resin are preserved and all requirements specified for enameled wire are met. Class 120 indicates a thermal class, requiring 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 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: 0.400mm and above and 1.600mm and below; ——Class 2: 0.400mm and above and 5.000mm and below. Refer to GB/T 23312.1-2009 for the nominal diameter of conductors Chapter 4.
