  • Publication number: 20210179806
    Abstract: A cable end is provided, such as an end of a cable for transporting electric energy. The cable end includes an electrically insulating layer obtained from a composition including at least: a polymer matrix, the polymer matrix being made up of one or more synthetic rubbers; a metal hydroxide as metallic filler, the metal hydroxide being present in the composition, such that for 100 parts by weight of composition, the metal hydroxide is present in a larger proportion by weight in the composition than the polymer matrix; a coupling agent between the polymer matrix and the metal hydroxide; and a plasticizer. A method of producing a cable end is also provided.

  • Publication number: 20180190412
    Abstract: The invention relates to a method for manufacturing a cable, including, from the inside to the outside, a central electrical conductor (1), a first semiconductor screen (2), an intermediate electric insulator (3), a second semiconductor screen (4), a metal screen (5) and an outer sheath (6), the method comprising a step of extruding a composition comprising at least one polyolefin for forming at least one layer constituting the first semiconductor screen, the intermediate electric insulator or second semiconductor screen and a step of cross-linking said layer. According to the invention, the method comprises the step of injecting, into the composition, a liquid solution containing at least one peroxide and at least one so-called cross-linking coagent, during the manufacture of said layer. The invention likewise relates to a cable manufactured by means of such a method.
