标准摘要
[中文适用范围]： 本国际标准对额定电压为 1 kV (Um = 1.2 kV) 和 3 kV (Um = 3.6 kV) 的电缆的短路最高温度限值提供了指导，涉及以下方面： - 绝缘材料; ——外护套和衬垫材料； ——导体和金属护套的材料和连接方法。附件的设计和安装条件对温度限制的影响都被考虑在内。电缆载流部件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 1kV (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.
