    • A device for establishing grounding of an installation of different types includes one or more cables, wherein a ground rail or a ground conductor, ground rails or ground conductors, or a ground point or ground points are grounded by the one or more cables including a combination of electrically conductive wires or conductors in at least one inner core and at least one outer layer which surrounds the inner core wholly or partly, and a bore extending, in at least one of ground and a rock, with a depth of more than 100 m. The one or more cables are laid in the bore. The electrically conductive wires or conductors in the at least one inner core include hundreds of thin conductors surrounded by the at least one outer layer that includes coarse conductors having a diameter at least two times more than a diameter of the thin conductors.
    • 用于建立不同类型的设备的接地的装置包括一个或多个电缆,其中接地线或接地导体,接地线或接地导体或接地点或接地点由一个或多个电缆接地,包括组合 在至少一个内芯中的至少一个导电线或导体,以及至少一个外部层,其全部或部分围绕内芯,以及在至少一个地面和岩石中延伸超过100μm的深度的孔 。 一根或多根电缆铺设在孔中。 至少一个内芯中的导电线或导体包括数百个由至少一个外层包围的薄导体,其包括直径比细导体的直径至少大两倍的粗导体。

    • Device for establishing an efficient grounding of an installation of different types includes one or more cables, wherein the ground rail or ground conductor, ground rails or ground conductors or ground point or ground points of the installation being grounded by the one or more cables including a combination of electrically conductive wires or conductors in at least one inner core and at least one outer layer which surrounds the inner core wholly or partly, and the cable or the cables are laid in one and the same or each in a separate bore in ground and/or rock of a considerable depth, preferably more than 200 m, e.g. 240 m or more.
    • 用于建立不同类型的安装的有效接地的装置包括一个或多个电缆,其中,所述设备的接地导体,接地导轨或接地导体或接地点或接地点由所述一个或多个电缆接地,所述电缆包括 在至少一个内核中的导电线或导体的组合以及至少一个外部层,其完全或部分地围绕内芯,并且电缆或电缆被放置在同一个或每个内部的单独的钻孔中, /或相当深度的岩石,优选大于200米,例如 240米以上。
