A multi-core cable is provided for connecting an electric device, in particular in a motor vehicle, for example for connecting a headlamp or control units in the headlamp. The cable features one or several first cores for the ground connection of the device and one or several further cores. The at least one further core does not run spirally and the at least one first core to the ground connection is wound spirally around the further cores. The cable does not feature any metal foil as shielding.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively.
