Abstract (en)

[origin: EP2765581A1] The cable (1) has an electrically insulating fluorinated polymeric layer (4) surrounding an elongated electrically conducting element (2), where the cable is free from a layer containing of polyimide between the conducting element and the polymeric layer. Two ribbon-shaped semiconductor fluorinated polymeric layers (3, 5) surround the conducting element, and the polymeric layer, respectively. The semiconductor layers are made of fluorinated polymer. The polymeric layer is an extruded layer, and surrounds one of the semiconductor layers.
