标准摘要
[中文适用范围]: 本国际标准对额定电压为 6 kV (Um - 7,2 kV) 至 30 kV (Um = 36 kV) 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 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.
英文名称Short-circuit temperature limits of electric cables with rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)
