  • Surface modified overhead conductor
    Patent number: 10586633
    Abstract: The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating is an inorganic, non-white coating having durable heat and wet aging characteristics. The coating preferably contains a heat radiating agent with desirable properties, and an appropriate binder/suspension agent. In a preferred embodiment, the coating has L* value of less than 80, a heat emissivity of greater than or equal to 0.5, and/or a solar absorptivity coefficient of greater than 0.3.
    Type: Grant
    Filed: April 30, 2015
    Date of Patent: March 10, 2020
    Assignee: General Cable Technologies Corporation

  • Electrical devices having polymeric members
    Patent number: 6524702
    Abstract: The present invention relates to electrically conductive devices comprising at least one electrically conductive substrate surrounded by an interpolymer composition. The interpolymer composition comprises at least one substantially random interpolymer comprising: (i) polymer units derived from: (a) at least one vinyl or vinylidene aromatic monomer, or (b) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; or (c) a combination of at least on vinyl or vinylidene aromatic monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; and (ii) polymer units derived from at least one aliphatic olefin monomer having from about 2 to about 20 carbon atoms. Such devices include, for example, wire and cable assemblies.

  • High performance power cable shield
    Patent number: 6291772
    Abstract: An improved shielding composition for power cables is disclosed. The composition includes a base polymer, conductive carbon black and various additives, including trimethylquinoline as an antioxidant in greater than conventional amounts. Cable shields prepared from the composition exhibit improved aging performance in accelerated cable life tests (ACLT).
