  • Patent number: 11205526
    Abstract: Linear low-density polyethylene polymers used to form covering layers for cables are disclosed. Such polymers exhibit certain molecular weight distributions suitable to form the covering layers for the cable. The polymer can be crosslinked to exhibit suitable properties including retained elongation at break values and hot set values.
    Type: Grant
    Filed: January 5, 2018
    Date of Patent: December 21, 2021
    Assignee: General Cable Technologies Corporation
    Inventors: Rubinder Kaur Lakhman, Jon Michael Malinoski, Sean William Culligan, Srinivas Siripurapu, Vijay Mhetar
  • Patent number: 11091573
    Abstract: A method of crosslinking a polyolefin resin with a silyl hydride crosslinking agent is disclosed. Crosslinkable compositions containing a polyolefin resin having about 0.9% to about 10% diene groups and a silyl hydride crosslinking agent are also disclosed.

  • Patent number: 9721701
    Abstract: A conductive composition can include a polyolefin base polymer, a high structure carbon black and a low structure carbon black. The conductive composition can exhibit two or more of a thermal conductivity of about 0.27 W/mK or more when measured at about 75° C., a volume resistivity of about 75 ohm-m or less when measured at about 90° C. and an elongation at break of about 300% or more. Cables having coverings formed of such conductive compositions and methods of making such cables are also described herein.

  • Publication number: 20150376369
    Abstract: A thermoset composition can include a cross-linked polyolefin; a primary filler selected from the group consisting of talc, calcined clay, or combinations thereof; a secondary filler selected from one or more of a metal oxide and a metal nitride, and one of a composition stabilizer and antioxidant. The thermoset composition can exhibit a thermal conductivity of at least about 0.27 W/mK, and/or a dielectric loss tangent of less than about 3% when measured at 90° C. The thermoset composition can be used in the construction on an insulation layer or jacket layer of a power cable.
