    • The present invention relates to a device comprising at least one electrical cable (10a, 10b, 10c) for transporting DC current, said electrical cable comprising an elongate electrical conductor (11a, 11b, 11c) surrounded by at least one first semiconducting layer (12c), an electrically insulating layer (13a, 13b, 13c) surrounding the first semiconducting layer and a second semiconducting layer (14a, 14b, 14c) surrounding the electrically insulating layer, characterized in that the electrical cable (10a, 10b, 10c) furthermore comprises a space charge trapping layer (15a, 15b, 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, 15c) replacing at least in part the second semiconducting layer (14a, 14b, 14c) of the electrical cable, so that the space charge trapping layer is in physical contact with the electrically insulating layer (13a, 13b, 13c) of the electrical cable.
    • 本发明涉及一种包括用于输送直流电流的至少一根电缆(10a,10b和10c)的装置,所述电缆包括由至少一个第一半导体层(11a,11b和11c)围绕的细长电导体 (12c),围绕所述第一半导体层的电绝缘层(13a,13b和13c)和围绕所述电绝缘层的第二半导电层(14a,14b和14c),其特征在于,所述电缆(10a,10b和 10c)还包括基于包含至少一种有机聚合物和至少一种线性填料的聚合物组合物获得的空间电荷捕获层(15a,15b和15c),空间电荷捕获层(15a,15b和15c) )至少部分地替代电缆的第二半导体层(14a,14b和14c),使得空间电荷捕获层与电绝缘层(13a,13b,a)物理接触 nd 13c)。
