标准摘要
[中文适用范围]: 本国际标准提供了关于额定电压高于 30 kV (Um = 36 kV) 的电力电缆的短路最大温度限制指南,直至 IEC 60141 和 IEC 62067 中给出的电压限制,涉及以下方面: - 绝缘材料; - 外护套和垫层材料; - 导体和金属护套材料及连接方法。 考虑了附件的设计以及安装条件对温度限制的影响。 电缆载流部件中允许短路电流的计算应按照 IEC 60949 进行。 [外文原描述]: Gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages above 30 kV (Um = 36 kV) up to the voltage limits given in IEC 60141 and IEC 60840, with regard to the following: - insulating materials; - oversheath and bedding materials; - conductor and metallic sheath materials and methods of connection. The design of accessories and the influence of the installation conditions on the temperature limits are taken into consideration. The calculation of the permissible short-circuit current in the current-carrying components of the cable should be carried out in accordance with IEC 60949.
