Abstract

Procédé permettant de réaliser l'étanchéité longitudinale à l'eau d'un câble électrique à isolation synthétique grâce à des cannelures pratiquées dans son écran semi-conducteur sur isolant et à une matière d'étanchéité dilatable en présence d'eau. On réalise des cannelures 5 sur l'écran semi-conducteur 11 sur isolant 4 et on introduit dans les creux de ces cannelures une matière d'étanchéité 8. On place ensuite l'écran métallique 9 et la gaine 10 de protection. Application à l'isolation des câbles monopolaires à moyenne tension et à isolation synthétique.Process for achieving longitudinal waterproofing of an electric cable with synthetic insulation by means of grooves made in its semiconductor-on-insulator screen and of a sealing material which can be expanded in the presence of water. Grooves 5 are produced on the semiconductor screen 11 on insulator 4 and a sealing material 8 is introduced into the hollows of these grooves. The metal screen 9 and the protective sheath 10 are then placed. Application to the insulation of monopolar cables at medium voltage and with synthetic insulation.
