Definitions

  • the monetary cost of copper is greater than other potential conductors such as aluminum, and the weight of copper per unit volume is also greater than other potential conductors, such as aluminum, which results in greater costs inherent in transporting and installing such conductors.
  • a conductor that mitigates against such inefficiencies and costs would be beneficial.
  • Figure 1 illustrates a cross-sectional view of conducting cable 100.
  • Figure 5 illustrates a cross-sectional view of hybrid conductor 424.
  • the total cross- sectional area of the wires 104a-104s and 108a-108r can be at least about 3000 kcmils. According to yet another aspect of the present teachings, the total cross-sectional area of the wires 104a-104s and 108a-108r can be at least about 3500 kcmils.
  • At least one of the wires used in the subset of wires or the complementary set of wires has an outer barrier including a nonconductive oxide of the material used.
  • aluminum wires can include an outer barrier of aluminum oxide and be combined with copper wires.
  • aluminum wires can be combined with chemically distinct aluminum alloy wires with both having a nonconductive outer barrier of aluminum oxide.
  • the wires 108 and wires 104 are shown twisted about the longitudinal axis A of the wire bundle 102 in opposing clockwise and counterclockwise directions relative to adjacent layers. According to another aspect of the present teachings, the wires 104, 108 can be wrapped or woven in different configurations.
  • one of the plurality of wires 104 includes the first conductive material and an insulating barrier 122.
  • the insulating barrier 122 is aluminum oxide, which is an electrical insulator.
  • Such an insulating barrier 122 can be generated, for example, by exposure of aluminum wire 104 to oxygen, which results in the aluminum on the surface of wire 104 undergoing oxidation to form an aluminum oxide outer insulating barrier 122.
  • the relative behavior of aluminum conductors increasing in cross-sectional size differs from that of copper conductors.
  • the first and second additional 1000 kcmil of aluminum provide lower additional amounts of ampacity than the corresponding additions of copper.
  • the third and fourth additional 1000 kcmil of aluminum provide more additional ampacity than the corresponding additions of copper. This due in significant part to the more pronounced skin effect characteristics of copper as compared to aluminum, which offsets the higher conductivity of copper at greater cross-sectional thicknesses.
  • addition of aluminum can provide more additional ampacity than a comparable addition of copper for cable having sufficient cross-sectional area.
  • the wires 819, 823 can be aluminum wires, copper wires, or a combination of both.
  • a layer of combined copper and aluminum wires such a layer can have a single layer of alternating adjacent copper and aluminum wire.
  • each circumferential layer, such as layers 818, 822 can have a radial thickness of more than one wire, such as by having a two or more strata of wires within a circumferential layer.
  • more than two additional circumferential layers such as layers 818, 822 can be disposed surrounding a conductor or conductors, such as the Milliken conductors 826 shown in Figure 8.
  • the wires 819, 823 in the circumferential layers 818, 822 can be enameled copper wires.
  • Such enameled wires 818, 822 can be implemented with the uncoated wires in Milliken segments 826.
  • stripping enamel from wires would only be required for enameled wires 818, 822, in preparation, for example, for splicing or termination.
  • Such a configuration would retain the benefit of eliminating the need to strip enamel from the wires in the Milliken segments 826.
  • the surrounding circumferential layers 906, 910 can each have a cross-sectional area of about 1000 kcmil or greater, 1500 kcmil or greater, or 2000 kcmil or greater.
  • Various ranges of cross-sectional areas for circumferential layers such as layers 906, 910 can be implemented according to the present teachings, such as between about 250 kcmil and about 2000 kcmil, or between 500 kcmil and about 1500 kcmil.
  • Adjacent circumferential layers, such as layers 906, 910 need not have the same thickness or cross-sectional size.

Abstract

L'invention concerne un câble conducteur moyenne ou haute tension qui peut comprendre au moins un conducteur entouré par une couche isolante. Une ou plusieurs couches de fils conducteurs peuvent entourer les couches isolantes, et les couches de fils conducteurs peuvent être elles-mêmes séparées par des couches isolantes. Le conducteur disposé au centre et les couches conductrices circonférentielles qui l'entourent peuvent comprendre du cuivre, de l'aluminium, ou une combinaison des deux. L'aire de section transversale du conducteur central peut aller d'environ 1000 kcmil à environ 4000 kcmil, et celle des couches de fils conducteurs qui l'entourent peut être d'au moins environ 250 kcmil.
