标准摘要
[中文适用范围]: 本国际标准提供了关于额定电压为 1 kV (Um = 1,2 kV) 和 3 kV (Um = 3,6 kV) 的电力电缆短路最大温度极限的指南,涉及以下内容: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极限的影响。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 of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV), with regard to the following: - insulating materials; - oversheath and bedding materials; - conductor and metallic sheath materials and methods of connection. The design and accessories and the influence of the installation conditions on the temperature limits are taken into consideration.
