11.8 Installation of electric cables

11.8 电缆的敷设
11.8.1. Electric and optical fibre cable runs are to be as far as practicable fixed in straight lines and in accessible positions.
11.8.1 电缆和光纤走线应尽实际可能成一直线固定在易于接近处。

11.8.2. Bends in fixed electric and optical fibre cable runs are to be in accordance with the cable manufacturer’s recommendations. The minimum internal radius of bend for the installation of fixed electric cables is to be chosen according to the construction and size of the cable and is not to be less than the values given in Table 2.11.6.
11.8.2 固定电缆和光纤走线中的弯曲应与电缆生产商的推荐一致。敷设固定电缆的最小弯曲内径,应按该电缆的结构和规格来选择,并不得小于表2.11.6中所列数值。
11.8.3. The installation of electric and optical fibre cables across expansion joints in any structure is to be avoided. Where this is not practicable, a loop of electric cable of length sufficient to accommodate the expansion of the joint is to be provided. For electric cables, the internal radius of the loop is to be at least 12 times the external diameter of the cable. For optical fibre cables, the internal radius of the loop is to meet the manufacturers’ minimum recommendations.
11.8.3 敷设电缆和光纤应避免跨越任何结构的伸缩接头部分。若确实不可避免时,则应设置一个其长度足以顺应该接头伸长的电缆回环。对于电缆来说,该回环的内径至少应为该电缆外径的12倍。对于光纤,该回环的内径至少应满足生产商的推荐值。

11.8.4. Electric and optical fibre cables for essential and emergency services are to be arranged, so far as is practicable, to avoid galleys, machinery spaces and other enclosed spaces and high fire risk areas except as is necessary for the service being supplied. Such cables are also, so far as reasonably practicable, to be routed clear of bulkheads to preclude their being rendered unserviceable by heating of the bulkheads that may be caused by a fire in an adjacent space.
11.8.4 用于重要设备和应急设备的电缆和光纤,应尽实际可行,避开厨房、机器处所和其它有高度失火危险的围蔽处所和区域,但对必须向这些处所中设备供电的电缆除外。此种电缆,还应尽合理实际可行,离开舱壁走线以排除由于相邻处所失火可能造成舱壁发热,而使其变得不能使用。

11.8.5. Electric cables having insulating materials with different maximum rated conductor temperatures are to be so installed that the maximum rated conductor temperature for normal operation of each cable is not exceeded.
11.8.5 绝缘材料具有不同的最高额定导线温度的多根电缆应敷设成使每根电缆不得超出其正常工作的最高额定导线温度。

11.8.6. Electric and optical fibre cables having a protective covering which may damage the covering of other cables are not to be bunched with those other cables.
11.8.6 具有保护覆层可能会损坏其它电缆覆层的电缆和光纤不应与这些其它的电缆集束在一起。

11.8.7. Cables having an exposed metallic screen, braid or armour are to be installed in such a manner that galvanic corrosion by contact with other metals is prevented. Sufficient measures are also to be taken to prevent damage to exposed galvanised coatings during installation.
11.8.7 具有暴露的金属屏蔽、编织或铠装的电缆安装时,应防止接触其他金属产生电腐蚀。也应采取充分的措施防止在安装过程中损坏暴露的镀锌层。
