标准摘要
[中文适用范围]: 本部分 IEC 60317 规定了基于聚酰胺-酰亚胺树脂单一涂层的 220 级漆包圆铜绕组线的要求,该涂层可以经过改性,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。220 级是一个热等级,要求最低温度指数为 220,热冲击温度至少为 240°C。温度指数对应的摄氏度温度不一定是推荐线材运行的温度,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: - 等级 1:0.071 mm 至 1.600 mm(含); - 等级 2:0.071 mm 至 1.600 mm(含)。标称导体直径在 IEC 60317-0-1 的第 4 条中规定。 [外文原描述]: IEC 60317-57:2010+AMD1:2024 CSV 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 .
