Two insulated signal conductors are wrapped in a double-helix fashion around a substantially straight third insulated ground conductor to form an interconnect. The first signal conductor is wrapped in a clockwise direction around the ground conductor. The second signal conductor is wrapped in a counter-clockwise direction around the ground conductor and first signal conductor, creating a spaced twisted-pair of the two signal conductors. The wrap frequency of the second conductor is lower than the wrap frequency of the first conductor. The difference in wrap frequencies of the first and second conductors is controlled such that the lengths of the first and second conductors are equal regardless of the length of the ground conductor. The wrap frequencies of the first and second signal conductors around the ground conductor are also chosen such that their intersections will be substantially orthogonal. The signal conductors can be composed of stranded wire in which the strands are straight as opposed to being twisted or braided with each other.
