The following is the opinions of ABS surveyor
1.All metallic coverings of power and lighting cables passing through hazardous areas or connected to equipment in such an area are to be earthed at least at each end. See 4-6-3/7.9 of SVR Under 90m.
2.For penetration through insulated, refrigerated space bulkheads, cables are to be installed in phenolic pipes or similar heat-insulating material joined to the bulkhead stuffing tube, or a section of such material is to be inserted between the bulkhead stuffing tube and the metallic pipe. See 4-6-3/5.27 of SVR Under 90m。
can you tell me ?

1.所有穿过危险区域或连接到类似区域的电力和照明电缆的金属编织需接地或至少两端接地。
2.穿越隔热或冷藏区域舱壁的电缆,需要敷设在酚醛管内,或管内有类似的热绝缘材料填充物,或者在金属管和穿舱管之间填充一段类似的材料。

第二点感觉翻译的有点问题,大体意思就是电缆要用热绝缘材料保护
仅供参考

大致意思懂了，第二条是说冷库的贯穿件需要绝热堵料填堵，冷库不可能走电缆管，冷库明线敷设的。对不对？
