IEC 60317-69:2017（E）规定了220级双涂层漆包矩形铝绕组线的要求。底层涂层基于聚酯或聚酯酰亚胺树脂，只要其保留原始树脂的化学特性并满足所有规定的线材要求，就可以对其进行改性。叠加涂层基于聚酰胺-酰亚胺树脂。本标准涵盖的标称导体尺寸范围为: 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中给出。 本出版物应与IEC 60317-0-9:20 15一起阅读 关键词:220类电气设备绕组用绝缘导线

IEC 60317-69:2017(E) specifies the requirements of enamelled rectangular aluminium winding wire of class 220 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide-imide resin. 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.
This publication is to be read in conjunction with IEC 60317-0-9:2015
