Gives guidance on the short-circuit maximum temperatur rating of electric cables having a rated voltage from 1,8/ 3 (3,6) kV to 18/ 30 (36) kV with regard to insulating materials, oversheath and bedding materials, conductor and metallic sheath materials and methods of connection. Takes into consideration the design of accessories and the influence of the method of installation on the temperature limit. Describes also the calculation of permissible short-circuit current in the current-carrying components of the cable.
