<p>The invention refers to a cable comprising twisted metallic conductors for use in digital systems, twisted metallic conductor cable with high electrical performance for use in digital systems formed by a bundled array of insulated metallic conductors of thermoplastic material sheathed in a protective banding and by a metallic shielding and finally by a protective cover. The cable uses simultaneously a series of pitches having the maximum and minimum values thereof comprised between 10 and 80 mm and a conductor insulation with a thickness from 2.0 to 2.2 times the conductor diameter for a dielectric constant of 1.87. The combination of the special sequence of pitches and an adequate insulation thickness provides a decrease in attenuation and an improvement concerning the problem of cross talk in digital data transmission.</p> |
