  • Patent number: 5122622
    Abstract: An electrical cable includes a central bearing part having a plurality of high-tensile plastic filaments. A rubber sheathing encloses the bearing part. An inner and outer conductor are twisted onto the sheathed bearing part and are disposed concentrically to one another. The inner and outer conductors each include stranded wires. The stranded wires of the inner conductor, as well as the stranded wires of the outer conductor, are twisted together to form a lay. The stranded wires of the inner conductor have the same number of lays as the stranded wires of the outer conductor but with opposite directions of lay. An inner separation layer covers the inner conductor and an outer separation layer covers the outer conductor. Additionally, a rubber insulation layer covers the outer separation layer. Finally, an outer covering encloses the outer separation layer.

  • Patent number: 4677256
    Abstract: So as to eliminate wind dependent displacements in control cables such as are used in container loading facilities, the weight of the cable itself is increased. To this end, braided-over lead cords are arranged in the central elements of each conductor bundle and in the corner spaces of the core. The load-carrying capacity of the carrier member is ensured by high tensile strength plastic filaments in the form of a braid and optionally in the form of corner fillings.
