IEC 60986 Ed. 2.1 b:2008

Gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages from 6 kV (U_m = 7,2 kV) up to 30 kV (U_m = 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.
