Abstract
A semiconductor packing substance for an undersea cable transporting electrical power, said cable having a core made of conductors 1 disposed axially, surrounded by a polyethylene layer 3 which is made semiconductive, then by a layer of insulating polyethylene (4). The packing substance is obtained by reticulating liquid nitrile rubber with carboxylic bonds and an epoxy resin to both of which is added a carbon black with a specific surface area at least equal to 100 m.sup.2 /g, an anti-oxidizing agent and a reticulation accelerator.
