核电站用1E级(K3类)电缆相关标准的讨论

Discussion on the Relevant Standards about Category 1E Class K3 Cables for Nuclear Power Station

目前我国核电建设已进入了快速发展的时期,核电站用电缆的需求也随之增加。由于我国还没有该类产品的国家标准,国内各企业在开发核电站用电缆过程中大多参照IEEE或RCC-E标准。本文按照GB22577—2008《核电站用1E级电缆通用要求》标准中关于1E级电缆的分类规定,介绍了国外标准及规范对于1E级(K3类)电缆的试验要求,供有关人员参考。

Now the construction of China＇ s nuclear power generation has entered a phase of rapid development. The demand for cables for nuclear power station in increasing accordingly. Due to absence of Chinese National standards about this kind of cables, related IEEE or RCC-E standards are mostly referenced by the domestic manufacturers in R ＆ D of nuclear power cables. In this paper, the test requirements for category 1E class K3 cables in foreign code and standard are presented according to the classification of category 1E cables in GB 22577--2008 Category 1E Cables for Nuclear Power Station; General requirements, in order to provide references for the testing persons concerned.
