Claim Text:
1. A star-quad cable for transmitting electrical signals comprising: at least two pairs of electrical conductors, each conductor having a core made of an electrically conductive material and a conductor sheath made of an electrically insulating material which surrounds the core in a radial position, the conductors being arranged at the corners of a square in a cross-section of the star-quad cable, the conductors making up a pair of said at least two pairs of electrical conductors being arranged at diagonally opposed corners of the square, said at least two pairs of electrical conductors being twisted together in a star-quad arrangement with a predetermined lay factor; a shield including an electrically conductive material which surrounds the two pairs of conductors on the outside radially being placed in position, the shield being constructed from a mesh of individual shield cores, and a second shield which is conductively connected to the shield electrically is arranged on the shield outside radially, wherein the second shield includes a mesh of individual second shield cores that are twisted in the opposite direction to the cores of the shield with a lay factor which corresponds to a lay factor of the cores of the shield; an insulator sheath including an electrically insulating material being arranged between the conductors and the shield; wherein at least one of said shield cores, or at least one bundle of said shield cores, is twisted to surround the conductors in a radial position such that said at least one twisted shield core or said at least one twisted bundle of shield cores extends substantially parallel to respective core of said electrical conductors in the axial direction, said at least one twisted shield core or said at least one twisted bundle of shield cores and said respective core of said electrical conductors extending in parallel to one another in the axial direction such that the at least one twisted shield core or the at least one twisted bundle of shield cores and the respective core of said electrical conductors lie on the same diagonal of the square at all points along the cross-section of the cable, and the at least one twisted shield core or the at least one twisted bundle of shield cores is arranged on a side of the core of said electrical conductors and is remote from the square.
