IEC 60317-93:2023规定了220级双涂层漆包矩形铜绕组线的要求。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。笔记？改性树脂是经过化学变化的树脂，或含有一种或多种添加剂以增强某些性能或应用特性的树脂。本标准涵盖的标称导体尺寸范围为: 宽度:最小。2.0 mm最大25.0 mm； 厚度:最小。最大0.80毫米。10.0毫米。 本规范包括1级和2级导线，适用于所有导线。IEC 60317-0-2中给出了宽度和厚度的规定组合以及规定的宽度/厚度比。本国际标准将与IEC 60317-0-2:20 20结合使用。

IEC 60317-93: 2023 specifies the requirements of enamelled rectangular copper winding wire of class 220 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which 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. NOTE？A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor dimensions covered by this standard is:
width: min. 2,0 mm max. 25,0 mm;
thickness: min. 0,80 mm max. 10,0 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specified width/thickness ratio are given in IEC 60317-0-2. This International Standard is to be used in conjunction with IEC 60317-0-2:2020.
