| 摘要 |
The present invention relates to a device comprising at least one electrical cable (10a, 10b, and 10c) for transporting DC current, said electrical cable comprising an elongate electrical conductor (11a, 11b, and 11c) surrounded by at least one first semiconducting layer (12c), an electrically insulating layer (13a, 13b and 13c) surrounding the first semiconducting layer and a second semiconducting layer (14a, 14b and 14c) surrounding the electrically insulating layer, characterized in that the electrical cable (10a, 10b, and 10c) furthermore comprises a space charge trapping layer (15a, 15b, and 15c) obtained on the basis of a polymeric composition comprising at least one organic polymer and at least one linear filler, the space charge trapping layer (15a, 15b, and 15c) replacing at least in part the second semiconducting layer (14a, 14b, and 14c) of the electrical cable, so that the space charge trapping layer is in physical contact with the electrically insulating layer (13a, 13b, and 13c) of the electrical cable. |
