  • LUBRICATED CABLE WITH REDUCED COEFFICIENT OF FRICTION
    Publication number: 20240167623
    Abstract: The present arrangement provides for an electric cable having at least one insulated conductor and a jacket surrounding the at least one insulated conductor. The polymer composition of the jacket includes at least a base polymer, a first lubricant and a second lubricant. The first lubricant is paraffin oil lubricant included in the polymer composition of the jacket in the range of 0.8%-2% by weight and the second lubricant is a siloxane lubricant included in the polymer composition of the jacket in the range of 0.25%-1.0% by weight.

  • Aluminum grounding cable for metal and non metal sheathed electrical cables
    Patent number: 8124875
    Abstract: An electrical power cable includes a conductor core having at least two insulated phase conductors twisted together and a binder tape configured to cover the twisted conductor core. A bare aluminum grounding conductor is laid longitudinally outside the binder tape, along the length of the conductor core and a metal armor is disposed around the grounding conductor and conductor core defining a metal armor for the electrical power cable.

  • Cable with an external extruded sheath and method of manufacturing of the cable
    Patent number: 7132604
    Abstract: A cable has a core, which is surrounded by an external extruded sheath. The core of the cable has at least one transmission element for the transmission of electrical current or telecommunication signals. The sheath comprises at least one flexible layer of a conventional, expanded material, this material having a tensile strength between 10.0 MPa and 50.0 MPa.
