A process of producing a yarn, ribbon or sheet comprising nanofibers that includes infiltrating a liquid into the yarn, ribbon or sheet and evaporating the liquid from the yarn, ribbon, or sheet to strengthen the yarn, ribbon or sheet. The yarn, ribbon, or sheet can be formed by solid-state draw from a carbon nanotube forest.

A mechanical assembly of a multi-strand cable including a plurality of strands and a substrate, the plurality of strands being aligned at the substrate in a first direction and the substrate having a convex edge in a plane perpendicular to the first direction. The plurality of strands is assembled on the substrate by swaging the strands around the convex edge, leading to the deformation of a portion of the strands around said convex edge. The substrate includes an opening in a plane substantially parallel to the first direction, the edge of which forms at least one portion of the convex edge. The swaging operation is carried out on the portion of the strands positioned between the edges of the opening such that a portion of the plurality of punched strands passes through the opening and projects around the convex edge onto the top and bottom sides thereof.

The present invention discloses electrical cables containing a cable core and a plurality of conductive elements surrounding the cable core. The cable core contains at least one composite core, and each composite core contains a rod which contains a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix, and surrounded by a capping layer.

A stranded electrical conductor includes a single center strand in aluminum or aluminum alloy (10, 20, 30, 40A, 50A) and a plurality of conductor strands (11, 21, 31, 41, 51) arranged in at least one layer around said center strand. The relation between the diameter of said center strand in aluminum or aluminum alloy and the diameter of said peripheral conductor strands is greater than or equal to 3.

In an electrical wire/cable a central wire (11) made of Aluminum is used. The central wire is surrounded by at least one wire of Copper (12) in direct contact with the central wire.
