+AMD1:2009 CSV 特种绕组线规范第22部分:180级聚酰胺涂覆的聚酯或聚酯亚胺漆包圆铜线

[中文适用范围]： 本部分IEC 60317规定了180级双层涂覆的圆形铜漆包线的要求。底层涂层基于聚酯或聚酯亚胺树脂，该树脂可以改性，前提是保留原始树脂的化学身份并满足所有规定的线材要求。上层涂层基于聚酰胺树脂。注：改性树脂是指经过化学变化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。180级是一个热级，要求最低温度指数为180，热冲击温度至少为200°C。对应于温度指数的摄氏温度不一定是推荐使用该线材的运行温度，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：等级1：0.050 mm 至 3.150 mm（含）；等级2：0.050 mm 至 5.000 mm（含）；等级3：0.250 mm 至 1.600 mm（含）。标称导体直径在IEC 60317-0-1的第4章中规定。 [外文原描述]： IEC 60317-22:2004+A1:2009 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. This consolidated version consists of the third edition (2004) and its amendment 1 (2009). This publication is to be read in conjunction with IEC 60317-0-1:2008 .
