DANSK DS/IEC 60724 PDF

This standard gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages from 1 kV (Um=1,2 kV) and 3 kV (Um=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 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 IEC 60949.
