Abstract

Manufacturing method of a longitudinally waterproof telecommunication cable, which has a core consisting of a plurality of conductors isolated by synthetic resin, in which a compound is introduced that prevents water from penetrating into the core or core, in the axial direction of the cable, within the interstices between the conductors and within the space between the core and the sheath, characterized in that a silicone rubber is introduced that vulcanizes at room temperature by the action of air humidity, inside of the interstices between the conductors and in the space surrounding the cable core, after which the cable core is provided with a tight fitting sheath.
