  • Publication number: 20120205137
    Abstract: An integrated power umbilical (K1) is shown. The power umbilical includes at least one power cable to transfer vast amounts of electric energy/power and filler material in the form of stiff, elongated plastic elements, laying at least partly around and between the power cables. These elements are collectively collected by means of a laying and closing operation into a twisted bundle, which in turn is enclosed by a protective sheath. At least one of the surrounding elements, i.e. the filler material or the sheath, is made of a semiconducting material, said semiconducting material being able to drain off capacitive currents arising in the power umbilical (K1) when the at least one power cable conducts vast amounts of electric energy/power.

  • Patent number: 8126303
    Abstract: A low cost, high performance, low profile flexible reinforcement member that can be used for both optical and copper communications cable. The reinforcement members made according to the preferred process are more rigid than known reinforcement members, but are less rigid than glass pultruded rods. Communications cables utilizing these members are lightweight and exhibit an improved combination of strength and flexibility compared to traditional communications cables. Further, these communication cables may then be installed into underground ducts using more economical and faster installation techniques.

    Abstract: A flexible electric line for movable loads is specified which has at least two wires, in each case consisting of an electrical conductor and an insulation surrounding it, as stranded elements which are stranded around a core consisting of insulating material with dents extending in the longitudinal direction in which the stranded elements lie. In the core, a non-metallic tension- and compression-resistant carrier enclosed by a layer of insulating material is centrally arranged. The layer of insulating material consists of an impressible material remaining permanently elastic, which completely fills the internal interstices between the stranded elements, and it is surrounded by a sliding layer of a material having good sliding characteristics compared with the stranded elements.

  • Publication number: 20110288388
    Abstract: A multiple-conductor electrical lead for use with medical device systems and a method of manufacture is disclosed. The multiple-conductor electrical lead comprises a central core and has at least one conductor, typically in the form of a ribbon cable, coiled around it along its length. Typically one or more ribbon cables coiled around a central core each comprise a plurality of separate electrical conductors both coupled together along their lengths in series and electrically insulated from one another with an insulating material. The material of the central core, e.g. polyester, stainless steel, nickel titanium, and the structural configuration, e.g. wrapping pitch of the ribbon cable around the central core and number of ribbon cables, are selected based on desired mechanical characteristics. Such multiple-conductor electrical leads are useful, for example, with analyte sensor systems such as amperometric glucose sensor systems used in the management of diabetes.
