Coaxial cable including tubular bimetallic inner layer with folded edge portions and associated methods

摘要

A coaxial cable may include an inner conductor, an outer conductor, and a dielectric material therebetween. The inner conductor may include a tubular bimetallic layer having a pair of opposing longitudinal edge portions at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto. At least one of the opposing longitudinal edge portions may define at least one folded edge portion including an end portion of the inner metal layer extending beyond a corresponding end portion of the outer metal layer and being folded adjacent thereto and defining a non-joined interface therewith. The longitudinal seam may include a welded joint between at least portions of the inner metal layer.
