特种绕组线规范. 第52部分: 芳香聚酰胺(聚芳酰胺)带包圆铜线, 温度指数为220

[中文适用范围]： 本部分 IEC 60317 规定了温度指数为 220 的带胶带缠绕圆铜绕组的线材的要求。绝缘由一层或多层不同厚度的芳香族聚酰胺（芳纶）胶带组成。 注：热冲击试验不适用于此类线材。因此，无法确定热冲击温度。因此，无法指定基于温度指数和热冲击温度要求的类别。 本标准涵盖的导体标称直径范围为： - 1.600 mm 至 5.000 mm（含）； - 导体标称直径见表 1。 [外文原描述]： IEC 60317-52:2014 specifies requirements for tape wrapped round copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. The range of nominal conductor diameters covered by this standard is: - 1,600 mm up to and including 5,000 mm; - the nominal conductor diameters are given in Table 1. This second edition cancels and replaces the first edition published in 1999. 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; - new 3.3, containing requirements for appearance; - modification to Clause 15 to delete the note on revisions to IEC 60172; - new Clause 23, Pin hole test. Keywords: tape wrapped round copper winding wire of temperature index 220, aromatic polyamide (aramid) tape
