IEC 60317-68:2017规定了120级漆包矩形铝绕组线的要求，其底涂层基于聚乙烯醇缩醛树脂，只要保留原始树脂的化学特性并满足所有规定的电线要求，就可以对其进行改性。本标准所涵盖的公称导体尺寸范围为 最低限度 最大值 宽度 2.0毫米 16.0 mm 厚度 0.80毫米 5.60毫米 1级和2级导线包含在IEC 60317的这一部分中，适用于所有导体。宽度和厚度的指定组合以及特定的宽度/厚度比在IEC 60317-0-9:20 15中给出。 关键词:电气设备绕组用绝缘导线120类

IEC 60317-68: 2017 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

	Minimum	Maximum
Width	2,0 mm	16,0 mm
Thickness	0,80 mm	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.
