Abstract: An electric cable has two groups of bundles including a first group of bundles connectable to a negative pole of a power source and a second group of bundles connectable to a positive pole of the power source, each of the groups of bundles include three bundles, each of the three bundles of each of the group of bundles include two bundles having a same smaller diameter and, a third bundle having a larger diameter and the two bundles of the three bundles of each of the groups of the bundles have at least one wire of a larger diameter, and the third bundle of the three bundles of each of the groups of the bundles has at least one wire of a smaller diameter.

Abstract: An electrical cable has a first plurality of bundles each including a plurality of wires and connectable to a positive pole of a current source at one end, a second plurality of bundles each including a plurality of wires and connectable with a negative pole of the current source at one end. The bundles of the first plurality of bundles and the second plurality of bundles include bundles of same diameters, the wires in the bundles have different diameters, and the wires of the bundles are twisted in opposite directions so that the wires having a greater diameter are twisted in one direction, while the wires a smaller diameter are twisted in an opposite direction.

Abstract: An electrical cable has a plurality of bundles extending in a direction of elongation and including three bundles associated with one another, preferably so that a transverse cross-section of the cable extending transversely to a longitudinal direction is substantially triangular, the bundles having different cross-sections, so that a bundle with a smaller cross-section is adapted to transmit a higher frequency current, while a bundle with a greater cross-section is adapted to transmit current with a lower frequency signal, the bundles having one end connectable to an electrical source and another end connectable to a single electrical consumer, so as to provide a range of frequencies.

Abstract: A phono-type plug has a center pin, a ground element, a barrel surrounding the ground element and the center pin, and an insulating element provided between the pin and the barrel, the insulating elements being provided with an extension which forms a strain relief supporting a wire.
