  • Patent number: 11495370
    Abstract: A cable includes insulated conductors arranged in a spaced apart generally coplanar configuration. A jacket encapsulates the insulated conductors. The jacket has a generally rounded rectangular cross-section, at least one spline along a minor edge of the jacket, and at least one channel along a major edge. An armor layer is applied about the jacket.

  • Publication number: 20220301740
    Abstract: Various cables for cable deployed electric submersible pumping systems and methods of manufacturing such cables are provided. The cable includes a power cable core and coiled tubing formed around the power cable core. The power cable core includes one or more conductors, insulation surrounding each conductor, and an elastomeric jacket extruded around the insulated conductors. Various mechanisms, systems, and methods are described to anchor the power cable core in the coiled tubing and to transfer weight from the power cable core to the coiled tubing.

  • Patent number: 10287826
    Abstract: A technique facilitates forming couplings along a power cable used, for example, to supply power to an electric submersible pumping system. In coupling the power cable to the electric submersible pumping system, a pothead may be provided with individual pothead bodies connected to individual conductors of the power cable. The pothead bodies are held with respect to each other by a plate structure which may be readily secured to a submersible motor of the electric submersible pumping system. If splices are formed along the power cable, individual potheads may be secured to conductor ends of the sections of power cable. The conductor ends are then inserted into corresponding individual adapters in a manner forming a secure and sealed connection.

  • Patent number: 9335249
    Abstract: Representative implementations of devices and techniques provide a tape adhesion test system. The test system applies a pulling force to an outer layer of tape adhered to an inner layer of tape through an adhesive bond, while the inner layer of tape is secured to a portion of the test system. The pulling force is measured when the adhesive bond between the outer layer of tape and the inner layer of tape breaks.

  • Patent number: 9336929
    Abstract: A power cable for artificial lift equipment can include one or more conductor assemblies, each including a copper conductor, a conductor shield with resistivity less than about 5000 ohm-m surrounding the conductor, insulation, an insulation shield having a resistivity less than about 5000 ohm-m surrounding the insulation, a metallic shield surrounding the insulation shield, and a polymer barrier surrounding the metallic shield. Such a cable may include a jacket molded about the one or more conductor assemblies and optionally armor surrounding the jacket. Various other apparatuses, systems, methods, etc., are also disclosed.
