    Abstract: A pre-twisted cable pair and a method for processing such pairs into an electrical cable having improved electrical and mechanical properties are disclosed. At least one insulated wire for transmitting electrical signals is pre-twisted prior to pairing with another insulated wire. As the pre-twisted wires are paired by a conventional double-twist machine which imparts back-twist, the detrimental electrical effects caused by irregularities in the individual wires are cycled over a very short distance, resulting in a cable pair having lower structural return loss, near-end crosstalk, and insertion loss than wires paired without any pre-twist. These pre-twisted wires may be united into a jacketed electrical cable by a continuous-extrusion jacketing process in which an optimal dielectric constant is maintained around each individual cable pair. This is made possible due to a unique die and tip configuration which provides ridges to space the pairs apart and provide optimum air dielectric, but prevents jacketing compound on the interior of the resulting electrical cable jacket from joining to isolate each individual cable pair during the extrusion process. The resultant electrical cable has superior electrical and mechanical properties when compared to similar electrical cables fabricated by conventional techniques.

    Abstract: Described is an electromagnetically shielded cable or line with insulated core conductors (1). The core conductors are surrounded individually or in pairs by metallic primary shielding (3). All the primary shieldings are surrounded by a common outer metal shielding (5) located directly over the primary shieldings. The whole assembly is enclosed in a protective sheath (6) made of insulating material which exerts radial forces, which depend on the material, on the outer metal shielding (5) and ensures that all the shieldings make contact with each other, i.e. the primary shieldings (3) with each other and also with the outer shielding (5).

    Abstract: The invention relates to an electric cable (300-1, 300-1a, 300-1b, 300-2) for coupling an electric power source (100e) with an electric load (300). The electric cable (300-1, 300-1a, 300-1b, 300-2) extends from an input end (E1) to an output end (E2) and comprises at least two sub-cables (310, 320, 330). Each sub-cable (310, 320, 330) comprises at least two electrically-conductive wires (L11..L33) laid out in a twisted or braided fashion. A first wire (L11, L21, L31) of said wires (L11..L33) is configured for carrying an electric signal (L1, L2, L3) from the input end (E1) to the output end (E2) of the sub-cable (310, 320, 330). A second wire (L12, L22, L32) of said wires (L11.L33) is configured for forming a current return path (IRC, IRC1, IRC2, IRC3) for the electric signal (L1, L2, L3) of the first wire (L11, L21, L31), wherein the second wire (L12, L22, L32) is electrically connected with a ground terminal (318) at the output end (E2) through an electrical connection (319). The invention provides for an electric cable that is much less susceptible to EMI enabling to feed much larger currents through the cable without causing undesired effects.
