The present invention provides a fully water blocked coaxial cable. In one preferred embodiment, the cable includes at least one metallic inner conductor and a dielectric material surrounding the inner conductor or conductors. A first metallic shield tape surrounds the dielectric material and the conductor or conductors. A first braided metallic shield surrounds the first metallic shield tape, and a second metallic shield tape surrounds the first braided shield. A water swellable flooding material is disposed between the first and second metallic shield tapes. A second braided metallic shield surrounds the second metallic shield tape, and a jacket surrounds the second braided metallic shield. In one preferred form of the invention, the water swellable flooding material includes at least one water swellable strand disposed between the first and second metallic shield tapes. More particularly, the water swellable strand may include a yarn having a coating of a water swellable hydrophilic material.

Water blocked shielded coaxial cable

A coaxial, fiber optic, or twisted pair cable having a is core surrounded by an armor layer and an outer protective jacket such that relative movement between the armor layer and the protective jacket is permitted. The armor layer has a pair of opposing longitudinal edge portions and is wrapped around a cable core such that a longitudinally extending seam is produced. The outer surface of the armor layer has an adhesive layer disposed thereon for bonding an outer protective jacket thereto. Portions of the outer surface of the armor layer adjacent the longitudinally extending seam are oxidized, thereby effectively neutralizing the adhesive layer. The oxidized portions of the armor layer reduce, if not eliminate, adherence between the protective jacket and the armor layer along the longitudinally extending seam.
