Abstract

a. Blindage pour câble électrique, notamment pour câble à haute et très haute fréquence. b. Blindage caractérisé en ce qu'il comporte au moins une couche dissipatrice d'énergie insérée entre deux structures conductrices dont l'une au moins peut revêtir la forme d'une couche conductrice ou d'un empilage de couches conductrices, les couches dissipatrices d'énergie étant constituées de matériaux dont la conductibilité est moindre que celle des matériaux constituant les structures conductrices, et qui provoquent, dans la gamme des fréquences pour lesquelles le blindage doit assurer une protection efficace, une dissipation d'énergie sous forme calorifique entraînant un affaiblissement d'au moins 6 décibels dans l'espace interblindage sur la longueur utile du câble. c. L'invention s'applique notamment aux câbles coaxiaux.
