Ageing and improvement of LV underground extruded cables systems

Extruded Low Voltage (LV) cables systems are ageing and an assessment of their condition is now necessary to build up a strategy regarding the management of this asset. This paper describes on the one hand the symptoms observed on faulty LV cables and branching joints by means of visual examination, material and electrical measurements in Laboratory. On the other hand, the paper describes the different investigations done in order to control and improve the quality of new LV extruded cable systems. (4 pages)
