电缆寿命要求 Requirements for Cable Service Life

2

本工程全部安全级和非安全级电缆使用寿命应不小于 40 年。 This project requires that the service life of all the security-level and non-security-level cables should be at least 40 years.

本技术规格说明书所提电缆使用寿命是基于电缆在线芯长期允许工作温度为90℃ 时的要求,对于 3.2 节所提到的“(部分 RRNS 类电缆所处环境温度 80-100℃)”不做 40 年寿命规定,但是厂家应该给出所供电缆分别在 80℃、85℃、90℃、95℃、100℃ 的长期运行环境温度条件是电力电缆(本工程电力电缆综合修正系数已按 0.5 取值)、控制电缆的寿命分析。分别给出上述温度时的电缆可能最大寿命,这一数据将作为工程实际应用中电缆更换的参考。 The requirement for cable service life mentioned in this technical specification is proposed based on the consumption that the long-term working temperature of the cable core is 90ºC. The 40-year service life requirement is not imposed on the case mentioned in section 3.2 where “the ambient temperature of some RRNS cables ranges from 80ºC to 100ºC”. In this case, however, the cable suppliers must provide the service life analysis of electrical cables and control cables under the long-term working temperatures of 80ºC, 85ºC, 90ºC, 95ºC, and 100ºC. (The comprehensive correction coefficient of electrical cables used in this project is 0.5.) .The possible maximum service life of cables under the preceding temperatures should be provided. The data will be used as a reference for cable replacement during project implementation.
