摘要
安全级电缆对核电站的安全运行和安全停堆起着十分重要的作用,核电站用的电缆一般具有以下特殊性能,如长期工作寿命、耐辐射、耐潮湿、低烟、无卤、阻燃等要求,因而对所采用电缆绝缘和护套材料以及试验都提出了很高的要求,本文针对核电站电缆选择时的一些要点进行了探讨。
The 1E cables are very important items for safety shutdown of the Nuclear Power Piant. Normally, cables installed in the Nuclear Power Plant should meet the requirements such as long life operation, radiation resistance, moisture resistance, low smoke, halogen free, flame retardant etc.. This will call for special requirements of cable insulation and jacket material, and test methods as well. The paper will discuss some key requirements of the nuclear cable.
