  • High and very high voltage DC power cable
    Patent number: 6509527
    Abstract: The high or very high voltage DC cable has extruded polymeric insulation made out of a styrene-containing material. The material of the insulation is constituted by a mixture comprising polyethylene, a hydrogenated block copolymer of styrene, and an anti-oxiding agent, with the styrene content by mass being 11% to 18%, and the material is not cross-linked. The cable is suitable for use as a DC power cable.
    Type: Grant

    Date of Patent: January 21, 2003
    Assignee: Nexans
    Inventors: Robert Gadessaud, Bernard Aladenize, Patrice Tran, Hakim Janah, Pierre Mirebeau, Daniel Acroute

  • Method and device for verifying that a given insulative element conforms to a reference insulative element
    Patent number: 5650620
    Abstract: A method of verifying that a given insulative element conforms with a reference insulative element, comprising the steps of: emitting a primary beam of electrons impinging on the given insulative element, receiving a secondary beam of electrons returned by the given insulative element in response to emission of the primary beam of electrons, and comparing a curve as a function of time of the electrical current of the secondary beam received with a curve as a function of time of a reference electrical current to establish whether or not the given insulative element conforms to a reference insulative element.

  • Process for the characterization of an insulator and the corresponding electron microscope
    Patent number: 5635715
    Abstract: Process and apparatus for the characterization of an insulator (5) at breakdown with the aid of an electron microscope (1), in which the electron flow rate of the beam (3) is adjusted as a function of in particular backscattered, lost, secondary or absorbed electrons. An automatic controller (9) sensitive to certain sensors (10,12) is provided for this purpose. The electron flow rate is proportional to the voltage to be simulated in the insulator.
