Gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages above 30 kV (Um = 36 kV) up to the voltage limits given in EN 60141 and EN 60840, 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 EN 60949.
