Short-circuit temperature limits of electric cables with rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)
额定电压为6 kV(Um = 7.2 kV)至30 kV(Um = 36 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 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.
