船舶电气装置 电气电缆的选择与安装

[中文适用范围]： IEC 60092的本部分提供了用于船舶固定电气系统的电气电缆选择、安装和操作条件的基本要求，适用于电压(U)最高至Um 18/30(36)kV的对称类别电缆和光纤电缆。 对固定系统的引用包括那些受到振动(由于船舶运动)或运动(由于船舶运动)影响的系统，不包括那些用于频繁弯曲的系统。 用于频繁或持续弯曲使用的电缆，能够承受机械应力和其所暴露的环境，在其他IEC规范中详细说明，如IEC 60227和IEC 60245。柔性电缆常用于可伸缩推进器、电梯、移动甲板、起重机、岸电连接和船舶上的其他移动应用。 不包括以下电缆类型和应用： – 海底和脐带电缆； – 电信和射频电缆； – 用于海上平台的电缆的选择和安装。 [外文原描述]： IEC 60092-352:2025 provides the basic requirements for the selection, installation and operating conditions of electrical cables intended for fixed electrical systems on board ships at voltages (U) up to and including Um 18/30 (36) kV, symmetrical category cables and fibre optic cables. The reference to fixed systems includes those that are subjected to vibration (due to the movement of the ship) or movement (due to motion of the ship) and not to those that are intended for frequent flexing. Cables subject to frequent or continual flexing use, which can withstand the mechanical stress and the environment they are exposed to, are detailed in other IEC specifications such as IEC 60227 and IEC 60245. Flexible cables are frequently used for retractable thrusters, elevators, moving decks, cranes, shore connections and other moving applications on board ships. This fourth edition cancels and replaces the third edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) modification of the part title; b) complete review of the document and establishment of the match with all other standards from the group IEC 60092-350 to IEC 60092-379; c) addition of terms and definitions; d) addition of technical requirements for the installation of symmetrical category cables with transmission characteristics up to 1 000 MHz; e) addition of the technical requirements for the installation of fibre optic cables; f) addition of technical requirements for the installation of cables for installation between areas with and without explosive atmospheres
