IEC 60724 Ed. 3.1 b:2008

Gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages of 1 kV (U_m = 1,2 kV) and 3 kV (U_m = 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.
