Abstract

L'invention porte sur un système en deux parties, destiné à limiter l'accumulation de charges électriques, et comportant un matériau déformable (20) de limitation des charges placé à la coupure du blindage de câbles à haute tension en attente (22), et un tube de réduction des charges (18) entourant le matériau déformable (20). L'invention porte également sur des données relatives aux paramètres de permittivité et de dimensionnement de ces deux éléments.
