Abstract
The present disclosure provides a concentric conductor for conducting electrical power from a source to a receiving system or load. The concentric conductor includes one or more conducting tubes interior to an outer tube, extending concentrically around a central axis. The conducting tubes are affixed a head-end interface and a connector assembly at either end of the concentric conductors.

A conductor rod, comprising:
- a first cylinder conductor extending along a longitudinal axis of the conductor rod, the first cylinder conductor having:
- a first inner diameter,
- a first outer diameter,
- a first terminal connector assembly affixed to the first cylinder conductor proximate a first end of the conductor rod, and
- a second terminal connector assembly affixed to the first cylinder conductor proximate a second end of the conductor rod;
- a barrel extending along the longitudinal axis of the conductor rod, the barrel having:
- a second inner diameter greater than the first outer diameter,
- a third terminal connector assembly affixed to the barrel proximate the first end of the conductor rod, and
- a fourth terminal connector assembly affixed to the barrel proximate the second end of the conductor rod;
- a head-end interface, the first terminal connector assembly being affixed to the head-end interface affixing the first cylinder conductor to the head-end interface, and, the third terminal connector assembly being affixed to the head-end interface affixing the barrel to the head-end interface;
- and
- a connector assembly, the second terminal connector assembly being affixed to the connector assembly affixing the first cylinder conductor to the connector assembly, and, the fourth terminal connector assembly being affixed to the connector assembly affixing the barrel to the connector assembly.

A method of assembling a conductor rod for use on a work machine, the method comprising:
- affixing a first cylinder conductor to a head-end interface by threading a first set of threaded members through the head-end interface into a first terminal connector assembly affixed to the first cylinder conductor, the first cylinder conductor having a first outer diameter;
- affixing a second cylinder conductor to the head-end interface by threading a second set of threaded members through the head-end interface into a second set of terminal connector assemblies affixed to the second cylinder conductor, wherein the second cylinder conductor has a second inner diameter and a second outer diameter, wherein the second inner diameter is greater than the first outer diameter of the first cylinder conductor defining a first cavity;
- affixing a barrel to the head-end interface by threading a third set of threaded members through the head-end interface into a third set of terminal connector assemblies affixed to the barrel, wherein the barrel has a third inner diameter and third outer diameter, wherein the third inner diameter is greater than the second outer diameter of the second cylinder conductor defining a second cavity;
- affixing the first cylinder conductor to connector assembly by threading a fourth set of threaded members through the connector assembly into a fourth terminal connector assembly affixed to the first cylinder conductor;
- affixing the second cylinder conductor to the connector assembly by threading a fifth set of threaded members through the connector assembly into a fifth set of terminal connector assemblies affixed to the second cylinder conductor;
- and
- affixing the barrel to the connector assembly by threading a sixth set of threaded members through the connector assembly into a sixth set of terminal connector assemblies affixed to the barrel.
