Abstract
A combination 37-wire unilay stranded conductor includes a 19-wire stable unilay construction includes two layers of wires on a core wire, each having a diameter D, to define a hexagon that circumscribes the 19 nineteen wires. A corner wire is positioned at each corner of the hexagon, the corner wires being formed to provide bearing surfaces facing radially outwardly and defining a circle having a diameter of approximately 4.7 D. A third layer of wires includes a smaller diameter wire having a diameter of approximately 0.8 D contacting each bearing surface, and pairs of two wires each having diameters D are positioned between the smaller wires and are nested in a recess formed by two wires in a preceding underlying layer to define a substantially circular outer cable configuration. The wires in the conductor are in contact with at least one wire in a previous inner layer and with circumferentially adjacent wires in the same layer thereby providing a stable conductor having a circular outer configuration without undesired gaps between adjacent wires in the third layer. A method and apparatus for making the 37-wire conductor are described.
