Abstract:
Cable, particularly for carrying high voltage direct current, comprising an electrical conductor, at least one semiconducting layer, a stratified insulating layer impregnated with an insulating fluid, and a metal sheath disposed on the outside of said insulating layer, characterized in that between said insulating layer and said metal sheath a layer for containing said insulating fluid is provided, comprising at least one winding of a tape made from a semiconducting elastomeric material having physical-chemical resistance with respect to said insulating fluid, said elastomeric material being such that a test specimen of said elastomeric material, kept under traction with an imposed elongation of 50% and immersed in said insulating fluid for 360 days at 85Â° C., has a permanent elongation of less than 35%.
