Patent number: 5171942Abstract: An oval or elliptical shaped overhead conductor that is twisted along its length to provide a continuously varying profile to the wind. A single core is comprised of a circular center wire wrapped by circular wires and the core is surrounded or encased by one or more layers of wire strands, including strands of different size from that of the core wires. Each layer is helically wound in a direction opposite to the underlying layers. The surrounding strands may be circular, with the strand sizes symmetrically arranged to result in a substantially oval or elliptical cross-section. Alternatively, the strands may be shaped into symmetrically arranged non-circular arcuate cross-sections, which when wound together result in an oval or elliptical conductor cross-section. The core strands are each circular or round wires having the same diameter, with the result that the core is easy and inexpensive to manufacture.Type: GrantFiled: February 28, 1991Date of Patent: December 15, 1992Assignee: Southwire CompanyInventor: Wilber F.

Patent number: 4843696Abstract: A method and apparatus for the high speed reshaping of round wire as it exits a drawing machine, but prior to its being collected on a bobbin or a stempack. The shape imparted to individual wires is such that as the preshaped wires are applied to a core by a stranding machine, a cable results in which there is substantially no interstitial space between the wires which add excessive bulk.Type: GrantFiled: May 11, 1987Date of Patent: July 4, 1989Assignee: Southwire CompanyInventors: Bobby C. Gentry, Bobby G. Workman, Wilber F. Powers, Jr., Gary W. Bradley
