    摘要： A cable for use in a predetermined voltage class includes at least one conductor; at least one extruded insulating layer surrounding the conductor, the insulating layer being made from a non-crosslinked insulating material having at least one thermoplastic polymer and at least one dielectric liquid, the insulating layer having a thickness such as to provide a voltage gradient on the outer surface of the cable insulating layer not smaller than 1.0 kV/mm; and a protective element around the extruded insulating layer having a thickness and mechanical properties selected to provide a predetermined impact resistance capability, the protective element having at least one expanded polymeric layer, the thickness being sufficient to prevent detectable insulating layer damage upon impact of at least 25 J energy. The insulating layer thickness and the protective element thickness can be selected in combination to minimize the overall cable weight while preventing detectable insulating layer damage upon impact of at least 25 J energy.

    摘要： An electrical cable (1) comprises a conductor (2), a possible inner coating layer (7) put directly into contact with the conductor (2), a self-repairing material layer (4) directly in contact with the inner coating layer (7), and an outer coating sheath (3) externally in engagement with the self-repairing material layer (4). Formed between the outer coating sheath (3) and the conductor (2) are anchoring portions (6) for the purpose of avoiding relative movements between the outer coating sheath (3) and the conductor (2).

    摘要： A telecommunication cable in which pairs of twisted together conductors are spaced apart to minimize capacitance unbalance and cross-talk. A central core member may be provided with the conductor pairs extending around the core member which may have spokes to separate the conductor pairs. Alternatively, the cable jacket has inwardly directed spacers which separate the conductor pins and hold them in recesses defined by the jacket.

    摘要： An electrical cable has a single yarn polyamide fiber strength member with a plurality of copper strands positioned adjacent thereto. An insulator jacket is extruded over the copper strands and the strength member to provide a insulated lead of high strength. A foam filler layer is extruded over a plurality of such leads, and a non-porous jacket is extruded over the foam filler layer, providing a light weight, flexible, high-strength, multi-lead cable, which is easily stripped by automated equipment.
