Buried long-distance low-attenuation-loss flexible armored symmetrical communication cable

The utility model relates to a buried long-distance low-attenuation-loss flexible armored symmetrical communication cable, which comprises a conductor, an insulating layer is uniformly coated on the side wall of the outer end of the conductor, and the copper conductor and the insulating layer jointly form a lead monomer. Every two groups of lead monomers with different colors are mutually twisted in pairs at a certain pitch to form a paired wire group, the outer side of each paired wire group is coated with a single-sided aluminum foil, copper foils are arranged among a plurality of groups of single-sided aluminum foils, the outer side of each copper foil is wound and connected with a copper foil, the outer side of each copper foil is woven by an electrical copper wire, the weaving density is greater than 80%, and the outer side of each copper foil is provided with an inner sheath. An inner sheath is arranged on the outer side of the cable, a middle isolation sheath is wound on the outer side of the inner she
