  • Paired electrical cable having improved transmission properties and method for making same
    Patent number: 6254924
    Abstract: A pre-twisted cable pair and a method for processing such pairs into an electrical cable having improved electrical and mechanical properties is disclosed. At least one insulated wire for transmitting electrical signals is pre-twisted prior to pairing with another insulated wire. As the pre-twisted wires are paired by a conventional double-twist machine which imparts back-twist, the detrimental electrical effects caused by irregularities in the individual wires are cycled over a very short distance, resulting in a cable pair having lower structural return loss, near-end crosstalk, and insertion loss than wires paired without any pre-twist. These pre-twisted wires may be united into a jacketed electrical cable by a continuous-extrusion jacketing process in which an optimal dielectric constant is maintained around each individual cable pair.
    Type: Grant
    Filed: January 8, 1998
    Date of Patent: July 3, 2001
    Assignee: General Cable Technologies Corporation
