  • Publication number: 20150107872
    Abstract: The present disclosure describes two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable, Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, alien crosstalk and return losses are improved, while the filler allows a cylindrical shape for optimized ground plane uniformity and stability for improved impedance and return loss performance.

The corrosion-inhibiting composition is preferably applied to the outer conductor of the coaxial cable, e.g., by wiping or by immersion, and heated to provide a corrosion-inhibiting coating that is not tacky or greasy.

  • Patent number: 6414239
    Abstract: An electrical power cable is provided, including an elongated carrier in the form of a soft center material hollow conduit. First and second insulated power conductors are spiraled about the conduit, with the first power conductor being spiraled in one direction, and the second power conductor being spiraled in the opposite direction. Preferably, the first and second power conductors cross one another at approximately a 90° angle. When the conductors are energized under load so that current flows through the power conductors, the magnetic field associated with the cable is reduced due to a cancellation effect because the power conductors are spiraled in opposite directions.

  • Patent number: 6246006
    Abstract: The present invention provides a non-braided shielded drop cable that can be easily attached to a standard connector. The cable includes a cable core including a center conductor and a dielectric layer surrounding the center conductor, a first electrically conductive shield surrounding the cable core and bonded thereto, a second electrically conductive shield surrounding the first shield, and a cable jacket surrounding the second shield and bonded thereto. An interstitial layer is located between the first and second shields and is composed of axially displaceable elongate strands and is typically composed of helically served yarns or metal wires. The present invention also includes a method of making a shielded cable.

  • Patent number: 6121547
    Abstract: A braided wire according to the present invention is constituted by weaving a plurality of first long conductors arranged in parallel and a plurality of second long conductors arranged in parallel so as to cross the first long conductors each other. Each of the first and second long conductors has a section which is perpendicular to an axis thereof and flattened such that a thickness of the conductor is decreased toward both end portions in a width direction. The first and second long conductors each having the flattened section are woven such that they are put one on another in a thickness direction.

  • Patent number: 6064000
    Abstract: A heat shrinkable shielding tube and a manufacturing method thereof employ an electromagnetic wave shielding material inserted into a heat shrinkable tube and adhered lengthwise thereto. A metallized fabric electromagnetic shielding material may be adhesively bonded inside the tube with a longitudinal stripe of adhesive. The longitudinal edges of the electromagnetic shielding material overlap to prevent electromagnetic leakage. Electrical wires or cables to be shielded are inserted into the shielding tube, and upon heating, the tube tightly engages the wires and provides effective electromagnetic shielding. The heat shrinkable shielding tube provides an outstanding effect in shielding electromagnetic wave radiation, and because the construction and manufacturing processes are flexible, it can also significantly reduce production costs.

  • Patent number: 6017626
    Abstract: The present invention features a high-temperature, automotive-wire article having a thin wall construction and an operative temperature of at least 135 degrees Centigrade. The wire article is made of an inner core of copper that is surrounded by a single layer of insulation, the latter of which includes an integral composite of two insulations. The inner layer of the composite consists of a fluorocarbon material; the outer layer of the composite is made of an irradiated, cross-linked polyolefin material. The outer layer may be irradiation cross-linked with between approximately 60 to 400 kGy, and preferably between 100 and 200 kGy. The inner and outer layers can optionally be adhesively bonded together or thermal fused together using a meltable resin, in order to form a single layer. The total wall thickness of the composite is less than approximately 0.5 mm.

  • Patent number: 6010788
    Abstract: A high speed data transmission cable comprises a pair of primary cables positioned adjacent to each other along their lengths with each primary cable including a pair of generally parallel conductors coupled together and surrounded by insulation. A shield layer surrounds each primary cable along its length to isolate the primary cables from each other. The primary cables and corresponding shield layers are twisted together around a center axis and form a double helical structure, thereby providing improved transmission characteristics in the high speed data transmission cable.

    Abstract: A winding element for an electrical machine, in particular a turbogenerator, includes an electrically conductive conductor configuration for carrying an electric current, an insulating layer surrounding the conductor configuration and a protective configuration surrounding the insulating layer. The protective configuration includes an isolating layer disposed like a helix, and an at least slightly electrically conductive contact layer likewise disposed like a helix and overlapping itself. The contact layer traverses or passes through the isolating layer from an inner side facing the insulating layer to an outer side facing away from the insulating layer. A winding assembly for an electrical machine includes an electrically conductive winding support and a winding element circumferentially surrounded and electrically contacted by the winding support.

  • Patent number: 5796045
    Abstract: The invention relates to a sleeve of braided sheath having at least one expanded end whose diameter is greater than the nominal diameter of the sheath; the expanded end includes a certain quantity of adhesive between its component filaments and it is surrounded, at least up to its free edge, by a ring of heat-shrink plastics material. The ring is shrunk in part only so as to be capable of being heat shrunk again once the sleeve has been put into place, thereby clamping the expanded end and fixing the position of said sleeve.

  • Patent number: 5777271
    Abstract: A coaxial, fiber optic, or twisted pair cable having a is core surrounded by an armor layer and an outer protective jacket such that relative movement between the armor layer and the protective jacket is permitted. The armor layer has a pair of opposing longitudinal edge portions and is wrapped around a cable core such that a longitudinally extending seam is produced. The outer surface of the armor layer has an adhesive layer disposed thereon for bonding an outer protective jacket thereto. Portions of the outer surface of the armor layer adjacent the longitudinally extending seam are oxidized, thereby effectively neutralizing the adhesive layer. The oxidized portions of the armor layer reduce, if not eliminate, adherence between the protective jacket and the armor layer along the longitudinally extending seam.
