规定了180级双涂层漆包圆铜绕组线的要求。底层涂层基于聚酯或聚酯亚胺树脂，可对其进行改性，前提是其保留原树脂的化学特性，并满足所有规定的电线要求。叠加涂层基于聚酰胺树脂。 180级是要求最低温度指数为180且热冲击温度至少为200°C的热级。 与温度指数对应的摄氏温度不一定是建议操作电线的温度，这取决于许多因素，包括所涉及的设备类型。 本标准涵盖的标称导体直径范围如下: -1级:0050毫米至3150毫米（含3150毫米）； -2级:0050毫米至5000毫米（含5000毫米）； -3级:0.250毫米至1600毫米（含1600毫米）。 IEC 60317-0-1第4条规定了标称导体直径。 与上一版相比，主要变化如下: -增加了新的外观要求，第3.2款； -击穿电压值，原表3，替换为参考IEC 60317-0-1； -增加了新的销孔试验，第23条。

Specifies the requirements of enamelled round copper winding wire of class 180 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 resin. Class 180 is a thermal class that requires a minimum temperature index of 180 and a heat shock temperature of at least 200°C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved. The range of nominal conductor diameters covered by this standard is as follows: - grade 1: 0,050 mm up to and including 3,150 mm; - grade 2: 0,050 mm up to and including 5,000 mm; - grade 3: 0,250 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1. The main changes with respect to the previous edition are listed below: - new requirements for appearance, Subclause 3.2, added; - breakdown voltage values, former Table 3, replaced with a reference to IEC 60317-0-1; - new pin hole test, Clause 23, added.
