Abstract (en)

[origin: WO2016001499A1] The invention concerns an electrical transmission cable comprising at least one composite central core (1A, 1B) formed from fibres embedded in a resin and around which there are disposed metal conductor wires (2, 3), said core (1) being coated with a coating layer (4) consisting of carbon black and/or carbon nanotubes embedded in a resin. According to the invention, the carbon black and/or carbon nanotube content is such that the resistivity of said coating layer (6, 5A, 5B) is less than or equal to 10+5 Ω.m.
