电气装置用电缆夹

[中文适用范围]： 本国际标准规定了用于固定电缆的电缆夹具和用于在电气安装中将电缆固定在一起的中间约束的要求和测试。电缆夹具在声明时提供对机电力的抵抗。本文件包括依赖制造商指定的安装表面进行电缆轴向和/或侧向固定的电缆夹具。 各种类型的电缆夹具和中间约束见附录A。 注：本文件中对制造商的要求在适用时也适用于进口商和责任供应商。 本文件不适用于电缆扎带。 [外文原描述]： IEC 61914:2021 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61914:2021 edition 3.0 and the previous IEC 61914:2015 edition 2.0. Futhermore, comments from IEC SC 23A experts are provided to explain the reasons of the most relevant changes. IEC 61914:2021 specifies requirements and tests for cable cleats used for securing cables in electrical installations and for intermediate restraints used for holding cables together in formation in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This document includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: requirements for mandrels used in testing rationalised and detailed in the general test requirements (Clause 5); definition of liner added and test requirements where liners and other optional parts are used; definitions for LV, MV and HV cables added and test requirements where MV & HV cable are used ; new corrosion resistance classes for plated products added; new requirements and test for durability and legibility of markings added; new test requirements for axial load testing of cleats for more than one cable added; lateral load test requirements for intermediate restraints added.
