电缆管理.电缆槽系统和电缆梯架系统

[中文适用范围]： 本文件规定了用于支撑和容纳电缆以及可能在电气和/或通信系统安装中的其他电气设备的电缆桥架系统和电缆梯系统的要求和测试。必要时，电缆桥架系统和电缆梯系统可用于将电缆分组。本文件不适用于导管系统、电缆槽系统和电缆管道系统或任何载流部件。 注：电缆桥架系统和电缆梯系统设计用作电缆的支撑，而不是作为外壳。 [外文原描述]： IEC 61537:2023 specifies requirements and tests for cable tray systems and cable ladder systems intended for the support and accommodation of cables and possibly other electrical equipment in electrical and/or communication systems installations. Where necessary, cable tray systems and cable ladder systems can be used for the arrangement of cables into groups. This document does not apply to conduit systems, cable trunking systems and cable ducting systems or to any current-carrying parts. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: new, repositioned and renumbered figures, revised classification for corrosion, revised SWL test types and procedures, new tests for lengths mounted vertical running horizontal and mounted vertical running vertical, tests for support devices: cantilevers, pendants, C shape ceiling supports and trapeze systems, new and revised annexes including use of tray as a protective earth conductor.
