  • Patent number: 6972376
    Abstract: In order to provide a flexible oxide superconducting cable which is reduced in AC loss, tape-shaped superconducting wires covered with a stabilizing metal are wound on a flexible former. The superconducting wires are preferably laid on the former at a bending strain of not more than 0.2 %. In laying on the former, a number of tape-shaped superconducting wires are laid on a core member in a side-by-side manner, to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer in a side-by-side manner, to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and provides flexibility to the superconducting wires and the cable formed therewith.

  • Patent number: 5043538
    Abstract: A water impervious cable construction for aerial, underground, or underwater use which includes at least one central electrical conductor, an overlayer of insulation material such as a plastic, a shield layer formed of a plurality of individual conductors (or the equivalent) which may be spirally wrapped and which shield layer is embedded in a layer of semiconducting material (which may also be a plastic), a layer of overlapped moisture barrier metal foil material, and a further overlayer of insulating material. The cable is manufactured on a substantially conventional cable extrusion line in which the partially manufactured cable (insulated core or cores wrapped with the shield conductors) is introduced into an extruder and a layer of semiconducting material is extruded thereon, wrapped with metal foil tape (which may include an edge located sealant), and introduced into a subsequent extruder to form one or more outer coatings.
