A data cable has a specially formed stranded conductor, as a result of which the transmission properties of the data cable are significantly improved. The stranded conductor is surrounded by insulation and has an unpressed assembly composed of a plurality of individual wires which are of a same type and being embodied as external wires and being disposed around a center. The external wires are embodied with a non-round cross section, with a result that when viewed in cross section an extent of the external wires increases radially outward from the center.
