Bundle twisted-pair cable

A cable includes a plurality of twisted pairs of conductors in a dense matrix-like form defining thereof horizontal rows and oblique columns with each other in a rectangular coordinate system wherein the twisted pairs in the same row have the same twist direction while having opposite twist directions with those in the two neighboring rows aside, and wherein for each row there is a local phase shift between every adjacent two pairs by following an equation of [60+(α/3)] or [120−(α/3)], and an initial arrangement in a first row has a global phase shift of [(5α/3)−60] and in a second row adjacent to said first row, has a global phase shift of −[(5α/3)−60], wherein α is an angle defined by every adjacent three twisted pairs which form an acute triangular cross-section.
