Gives guidance on the short-circuit maximum temperature limits of electric cables having rated voltages of 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 and accessories and the influence of the installation conditions on the temperature limits are taken into consideration. Donne des indications sur les limites de temperature maximales de court-circuit des cables electriques de tension assignees de 1 kV (Um = 1,3 kV) et 3 kV (Um = 3,6 kV), en ce qui concerne: - les materiaux disolation; - les materiaux de gainage et de bourrage; - les materiaux de lame et de la gaine metallique et les methodes de raccordement. La conception des accessoires et linfluence des conditions dinstallation sur les limites de temperature sont prises en compte.
