Gives manual methods for calculating cyclic rating factors for cables whose internal thermal capacitance cannot be neglected; in general this applies to cables for voltages greater than 18/30 (36) kV. It also gives a method for calculating the emergency rating for cables of any voltage. Fournit des methodes manuelles de calcul des facteurs de capacite de transport en regime cyclique pour des cables dont la capacite thermique interne ne peut pas etre negligee, il sagit generalement de cables de tensions superieures a 18/30 (36) kV. Donne egalement une methode de calcul des capacites de transport en regime de secours pour des cables de tout niveau de tension.
