标准范围

IEC 60317-25:2020作为IEC 60317-25:2020 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60317-25:2020规定了200级双涂层漆包圆铝绕组线的要求。底层涂层基于聚酯或聚酯酰亚胺树脂，只要保留原始树脂的化学特性并满足所有规定的电线要求，就可以对其进行改性。叠加涂层基于聚酰胺-酰亚胺树脂。注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。本文件涵盖的公称导体直径范围为:-1级:0,250 mm至3,150 mm并包括3,150 mm；-2级:0,250 mm至5,000 mm（含5,000 mm）。标称导体直径在IEC 60317-0-3:20 08和IEC 60317-0-3:20 08/AMD1:2013的第4条中规定。第四版取消并取代了2010年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-新的3.2.2载有关于绕组线的一般说明，以前是范围的一部分；-修订第11条，以考虑中间标称导体直径；-修订第7条，以指明弹性测试是不适当的。-修订第16条，仅规定可提取物的百分比和最小保留介电击穿电压。

IEC 60317-25:2020 is available as IEC 60317-25:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-25:2020 specifies the requirements of enamelled round aluminium winding wires of class 200 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which can be modified provided 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 diameters covered by this document is:
- Grade 1: 0,250 mm up to and including 3,150 mm;
- Grade 2: 0,250 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-3:2008 and IEC 60317-0-3:2008/AMD1:2013. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- new 3.2.2 containing general notes on winding wire, formerly a part of the Scope;
- revision to Clause 11 to take into account intermediate nominal conductor diameters;
- revision to Clause 7 to indicate that the springiness test is inappropriate.
- revision to Clause 16 to specify only the percentage of extractable matter and the minimum retained dielectric breakdown voltage.
