Abstract

L'invention concerne une amélioration des barrières d'étanchéité pour câbles de transport d'énergie. La feuille métallique mince qui forme écran entre la couche semi-conductrice externe et la couche d'isolant externe reçoit, sur au moins un de ses bords, une couche d'enduit adhésif thermoplastique qui assure son scellement lors de la fabrication du câble. Application aux câbles d'énergie destinés à être enterrés.
