标准摘要
[中文适用范围]: 本国际标准提供了关于额定电压从 6 kV (Um = 7,2 kV) 到 30 kV (Um = 36 kV) 的电力电缆短路最大温度限制的指导,涉及以下方面: - 绝缘材料; - 护套和垫层材料; - 导体和金属护套材料以及连接方法。 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 from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV), 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.
