用于电气装置的电缆夹

[中文适用范围]： IEC 61914:2015 RLV 包含国际标准及其红线版本。 Redline 版本为您提供了一种快速、简单的方法来比较该标准与其先前版本之间的所有更改。 Redline 版本不是正式的 IEC 标准，只有当前版本的标准才被视为正式文件。 IEC 61914:2015 规定了电气装置中用于固定电缆的电缆夹和中间约束装置的要求和测试。电缆夹可抵抗所声明的机电力。该标准包括依靠制造商指定的安装表面来轴向和/或横向固定电缆的电缆夹。第二版取消并取代了 2009 年发布的第一版。该版本构成了技术修订。相对于前一版本，该版本包括以下重大技术变化： a) 根据相关新数据的锁片安装方向，对侧向负载保持力进行附加声明和测试； b) 任何短路试验中电缆中心之间的距离和相关新数据的附加声明； c) 短路试验所用电缆的规格和试验环境温度限制的放宽； d) 附加要求在测试前后拍摄短路测试装置并记录所用电缆的更完整的细节； e) 修改了耐紫外光测试的参数。该版本还包括相对于前一版本的以下编辑修改： f) 修订和更新的规范性参考文献和参考书目； g) 定义的编辑澄清； h) 对测试样品的选择和为多根电缆设计的夹板测试的程序进行编辑澄清； i) 放宽了部分芯轴材料要求； j) 澄清短路测试后的检查要求，并添加第二次短路后交流或直流电压测试的选项； k) 澄清耐腐蚀测试适用于所有类型的固定； l) 新的防滑板示例插图。 [外文原描述]： IEC 61914:2015 RLV contains the International Standard and its Redline version. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document. IEC 61914:2015 specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This standard includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Additional declaration and test for lateral load retention depending on cleat mounting orientation with associated new figures; b) Additional declaration of the distance between the cable centres in any short-circuit test and associated new figures; c) Specification of the cable to be used in short-circuit testing and relaxation of the ambient temperature limits for the test; d) Additional requirement to photograph the short-circuit test arrangement before and after the test and to record more complete details of the cable used; e) Revised parameters for the test of resistance to UV light. This edition also includes the following editorial changes with respect to the previous edition: f) Revised and updated normative references and bibliography; g) Editorial clarification of definitions; h) Editorial clarification of procedures for selection of test samples and the testing of cleats designed for more than one cable; i) Relaxation of some mandrel material requirements; j) Clarification of the inspection requirements following a short-circuit test and adding the option of either a.c. or d.c. voltage testing following a second short-circuit; k) Clarification that the resistance to corrosion test applies to all types of fixing; l) New cleat example illustration.
