Short-circuit temperature limits of electric cables with rated voltages of 1 kV (<i>U</i><sub>m</sub> = 1,2 kV) and 3 kV (<i>U</i><sub>m</sub> = 3,6 kV)
额定电压为1 kV(<i>U</i><sub>m</sub>=1,2 kV)和3 kV(<i>U</i><sub>m</sub>=3,6 kV)的电缆的短路温度极限
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.
