标准摘要
[中文适用范围]: 本国际标准对额定电压高于 30 kV (Um = 36 kV) 直至 IEC 60141 和 IEC 60840 中给出的电压限值的电缆的短路最高温度限值提供了指导,涉及以下内容: - 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 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.
