标准摘要
[中文适用范围]： 本部分IEC 60317规定了120级矩形铝绕组线的要求，该线材具有基于聚醋酸乙烯酯或聚乙烯醇缩甲醛树脂的单一涂层，可以进行改性，前提是保持原始树脂的化学特性并满足所有规定的线材要求。 注1：改性树脂是经过化学变化的树脂，或含有一个或多个添加剂以增强某些应用性能特性的树脂。 注2：聚醋酸乙烯酯是通过聚乙烯醇与醛缩合产生的一系列热塑性乙烯基树脂的通用名称。例如聚醋酸乙烯酯、聚乙烯醇缩甲醛和聚乙烯醇缩丁醛。 本标准涵盖的标称导体尺寸范围为： 宽度：最小2.0毫米，最大16.0毫米 厚度：最小0.80毫米，最大5.60毫米 本部分IEC 60317包括1级和2级线材，适用于所有导体尺寸。 宽度和厚度的特定组合以及宽度/厚度的特定比例在IEC 60317-0-9中给出。 [外文原描述]： IEC 60317-68:2017+A1:2019 specifies the requirements of enamelled rectangular aluminium winding wire of class 120 with a sole coating based on polyvinyl acetal resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor dimensions covered by this standard is Width: minimum 2,0 mm and maximum 16,0 mm Thickness: minimum 0,80 mm and maximum 5,60 mm Wires of grade 1 and grade 2 are included in this part of IEC 60317 and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specific ratio width/thickness are given in IEC 60317-0-9:2015. This consolidated version consists of the first edition (2017) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
