Abstract

A conductor for conducting electric current has along its length at least two main sections comprising at least a first main section and a second main section and at least one transposing junction connecting adjacent ones of the main sections The conductor comprises several partial conductors comprising at least a first partial conductor and a second partial conductor wherein in the first main section the first partial conductor has an outer diameter which is larger than an outer diameter of the second partial conductor and, in the second main section the second partial conductor has an outer diameter which is larger than an outer diameter of the first partial conductor.

First claim

The invention claimed is:

1 . A conductor for conducting electric current, comprising along its length at least two main sections comprising a first main section and a second main section, and comprising at least one transposing junction connecting adjacent ones of the main sections,
the conductor comprising at least two partial conductors comprising at least a first partial conductor and a second partial conductor, each of the partial conductors running through the main sections and the transposing junction and being electrically insulated from each other in the main sections and the transposing junction, each of the partial conductors having in each of the main sections an outer diameter, wherein in the first main section, the outer diameter of the first partial conductor is larger than the outer diameter of the second partial conductor, and in the second main section the outer diameter of the second partial conductor is larger than the outer diameter of the first partial conductor, wherein the conductor comprises a first portion and a second portion, each of the portions comprising the at least two main sections and the at least one transposing junction between the main sections, and comprising a joining junction between the portions, wherein in the joining junction the partial conductors are electrically connected to each other and wherein in the at least one transposing junction the partial conductors remain continuously electrically insulated from each other.

2 . The conductor of claim 1 ,
wherein in the first main section the first partial conductor has a shape of a cylinder having a first outer radius and the second partial conductor has a shape of a cylinder of a second outer radius, wherein the first outer radius is larger than the second outer radius.

3 . The conductor of claim 1 ,
wherein in the first main section the first partial conductor encloses the second partial conductor and in the second main section the second partial conductor encloses the first partial conductor.

4 . The conductor of claim 1 , wherein an interior structure of the conductor is identical in the main sections and wherein the main sections have the same lengths.

5 . The conductor of claim 1 , wherein in each of the main sections the partial conductors have a constant geometry along the length of the respective main section.

6 . The conductor of claim 1 , wherein in the transposing junction each of the partial conductors has one or more openings in its wall to enable one or more transposing portions of the other one of the partial conductors to cross the wall.

7 . The conductor of claim 1 , wherein the partial conductors are separated by gaps from each other, wherein the gaps are air gaps and/or insulating inserts.

8 . The conductor of claim 1 , wherein the partial conductors are only electrically connected at the joining junction.

9 . The conductor of claim 1 , wherein each of the partial conductors is formed as a single, integrally formed piece.

10 . The conductor of claim 1 , having a bend being provided by the joining junction electrically connecting the partial conductors or being provided by the transposing junction changing the outer diameters of the partial conductors.

11 . The conductor of claim 1 , wherein the conductor comprises:
a number of the partial conductors, the number being larger than two; and a number of the main sections, wherein adjacent ones of the main sections are connected by one of the at least one transposing junction, wherein the number of the main sections is a multiple of the number of the partial conductors.

12 . The conductor of claim 1 , wherein in each of the main sections each of the partial conductors has a tubular shape.

13 . A method of manufacturing the conductor of claim 1 , wherein at least a part of the conductor is manufactured by an additive manufacturing method or by a molding method.

14 . The method of claim 13 , wherein the conductor is at least partially formed by casting, wherein an insert is positioned in a mold, wherein the insert provides gaps insulating the partial conductors from each other.

15 . A use of the conductor of claim 1 for conducting electric current with an alternating current (AC) component.

16 . The use of the conductor of claim 15 wherein in the first main section of the conductor the first partial conductor has a shape of a cylinder having a first outer radius and the second partial conductor has a shape of a cylinder of a second outer radius, wherein the first outer radius is larger than the second outer radius.

17 . The use of the conductor of claim 15 , wherein in the first main section of the conductor, the first partial conductor encloses the second partial conductor and in the second main section the second partial conductor encloses the first partial conductor.

18 . The use of the conductor of claim 15 , wherein an interior structure of the conductor is identical in the main sections of the conductor and wherein the main sections have the same lengths.

19 . The use of the conductor of claim 15 , wherein in each of the main sections of the conductor, the partial conductors have a constant geometry along the length of the respective main section.

20 . The use of the conductor of claim 15 , wherein in the transposing junction each of the partial conductors has one or more openings in its wall to enable one or more transposing portions of the other one of the partial conductors to cross the wall.
