Cable with multiple pairs of parallel symmetrical axes

Abstract

The invention relates to a cable with multiple pairs of parallel symmetrical axes. The cable with the multiple pairs of parallel symmetrical axes comprises 4-32 pairs of parallel symmetrical axis core line and outer sleeve layers wrapping the parallel symmetrical axis core line, and each outer sleeve layer comprises a protective sleeve layer, a woven layer, an aluminum foil shielding layer and a polyester wrapping tape layer from outside to inside. Each parallel symmetrical axis core line pair comprises two center lines which are arranged in parallel and an electric drainage wire, the aluminum foil shielding layer wraps each parallel symmetrical in a winding mode, and each center wire comprises a foam insulating layer and a silver-plated copper center conductor which is arranged in the center of the foal insulating layer and squeezes and wraps the foam insulating layer. The cable with the multiple pairs of parallel symmetrical axes has the advantages that improvement of the transmission rate of signals is achieved, the number of transmission passageways is increased from the current 1 or 2 to 4-32, the overall performance of anti-electromagnetic interference can be greatly improved, cross talk indicators inside the line pairs or among the wire pairs can be effectively reduced due to independent shielding of the line pair and two-layer composite shielding outside an overall cable core, and the stable high-frequency transmission performance of products can be ensured.
