Abstract
Procedure to protect an underwater electrical cable from the corrosion action of the outermost metallic parts that it is endowed with exerted by fluids eventually present in the medium in which the cable is immersed, said cable being provided externally with a suitable metallic element armor to withstand mechanical stresses applied to the case itself, characterized by the fact that a continuous protection element is arranged around the cable, which is substantially impervious to said fluids, so as to constitute a first barrier to crossing of these, and which comprises at least one material in which heavy metal compounds capable of reacting with the part of said fluids that penetrate said element are incorporated, to give rise to chemically inert reaction products with respect to said metallic parts of the cable, so as to constitute a second barrier to the crossing d and the fluids themselves.
