额定电压为1kV(Um=1.2kV)和3kV(Um=3.6kV)的电缆的短路温度极限

Short-circuit temperature limits of electric cables with a rated voltage of 1 kV (U_m = 1,2 kV) and 3 kV (U_m = 3,6 kV)

IEC 60724-2000 发布历史

This International Standard 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 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.
