额定电压 1 kV (Um = 1 2 kV) 至 30 kV (Um = 36 kV) 挤包绝缘电力电缆及其附件 第4部分：额定电压 6 kV (Um

[中文适用范围]： IEC 60502的本部分规定了符合IEC 60502-2的额定电压从3@6/6（7@2）kV至18/30（36）kV@的电力电缆附件型式试验的试验要求。不包括用于特殊应用@的附件，例如架空电缆@海底或船舶电缆或危险情况（爆炸性环境@耐火电缆或地震条件）@。以前，现在此 IEC 标准涵盖的产品的批准是基于国家标准和规范和/或令人满意的服务性能的证明。本 IEC 标准的发布并不会使现有的批准失效。然而，根据这些早期标准或规范批准的产品不能声称获得了该 IEC 标准的批准，除非专门对其进行了测试。一旦成功完成，就没有必要重复这些测试，除非材料@设计或制造过程发生变化，这可能会影响性能特征。测试方法包含在 IEC 61442 中。 [外文原描述]： Specifies the test requirements for type testing of accessories for power cables with rated voltages from 3,6/6 (7,2) kV up to 18/30 (36) kV, complying with IEC 60502-2. Accessories for special applications, such as aerial cables, submarine or ship cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions), are not included. Formerly, approvals of products now covered by this IEC standard have been achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. The publication of this IEC standard does not invalidate existing approvals. However, products approved according to these earlier standards or specifications cannot claim approval to this IEC standard unless specifically tested to it. It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process which might affect the performance characteristics. Test methods are included in IEC 61442. Significant technical changes with respect to the previous edition are as follows: a) the scope clarifies the validation of former product approvals; b) definitions have been given for tracking, erosion and metallic housing, and substantial damage has been more detailed; c) the range of approval has been revised; d) test sequences have been simplified by removing initial heating cycles; e) additional information has been provided for testing separable connectors with a metallic housing; f) an examination has been added to all test sequences for information only.
