Abstract

An electrical conductor comprises three or more solid segments of identical shape. In cross-section, each segment comprises two sides, which are configured for flush bearing against correspondingly opposing lateral surfaces on another segment. The cross-sectional surface through all the constituent segments of the electrical conductor is describable by a closed curve having a stepless characteristic. All the constituent segments of the electrical conductor are stranded in combination.

First claim

The invention claimed is:

1. Electrical conductor comprising: three or more solid segments of identical shape, wherein each segment comprises two lateral surfaces, which are configured for flush bearing against correspondingly opposing lateral surfaces on another segment, wherein the cross-sectional surface through all the constituent segments of the electrical conductor is describable by a closed curve having an essentially stepless characteristic,
wherein the segments, on the lateral surfaces, which rest against each other, incorporate profiles which permit the mutual arrangement thereof in the unstranded state and which, in the stranded state, link the segments in a continuous, permanent and form-fitted manner,
wherein the profiles only permit the arrangement, of a final individual segment to the other segments of the conductor, in a single direction that is substantially parallel to one lateral surface that bears the profiles, the single preferred direction extending radially from a longitudinal axis of the electrical conductor,
and wherein all the constituent segments of the electrical conductor are stranded in combination.

2. Electrical conductor according to claim 1 , wherein the cross-sectional surface is circular.

3. Electrical conductor according to claim 1 , wherein the solid segments of identical shape are configured in a flush arrangement around a central element of a different shape.

4. Electrical conductor according to claim 1 , wherein a separating layer is arranged between the three or more segments, which prevents any material bonding of the segments.

5. Electrical conductor according to claim 1 , wherein a layer of a material which swells upon contact with a fluid is arranged between the segments.

6. Electrical conductor according to claim 1 , wherein the electrical conductor is enclosed by an outer sheathing.

7. Electrical conductor according to claim 6 , wherein the outer sheathing is formed of a material which swells upon contact with a fluid.

8. Electrical conductor according to claim 6 , wherein the outer sheathing is formed of an electrically conductive or semi-conductive material.

9. Electrical conductor according to claim 6 , wherein the outer sheathing is formed of a strip material which is spirally wound around the electrical conductor.

10. Electrical conductor according to claim 6 , wherein the outer sheathing encloses the electrical conductor in a continuously seamless manner.

11. Electrical conductor according to claim 1 , wherein the profiles permit the arrangement of the final individual segment while all other segments are in their final position with respect to the completed conductor.

12. Electrical conductor according to claim 1 , wherein the profiles prevent a movement of two adjacent segments in a direction perpendicular to the lateral surface that bears the profile, when the segments are in their final position with respect to each other.
