标准摘要
[中文适用范围]: IEC 60317 的这一部分规定了带有基于聚酰胺酰亚胺树脂的唯一涂层的 220 级漆包圆铜绕组线的要求,如果它保留原始树脂的化学特性并满足所有指定的电线要求,则可以对其进行修改。 220 级是耐热等级,要求最低温度指数为 220,热冲击温度至少为 240 °C。与温度指数相对应的摄氏度温度不一定是建议操作电线的温度,这将取决于许多因素,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:0.071 mm 至 1,600 mm(含); – 2 级:0.071 毫米至 1,600 毫米(含)。 IEC 60317-0-1 第 4 条规定了标称导体直径。 [外文原描述]: IEC 60317-57:2010 specifies the requirements of an enamelled round copper winding wire of class 220 with a sole coating based on polyamide-imide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. Class 220 is a thermal class that requires a minimum temperature index of 220 and a heat shock temperature of at least 240 °C. This publication is to be read in conjunction with IEC 60317-0-1:2008.
