Abstract

Galloping motion disruptors and methods for reducing conductor galloping are provided. A galloping motion disruptor includes a first disruptor rod and a second disruptor rod. Each of the first and second disruptor rods includes a first end portion, a second end portion, and a mid-section between the first end portion and the second end portion. The first end portion includes a helical gripping section. The second end portion includes a hook section. The hook sections of the first and second disruptor rods are connectable to each other.

First claim

What is claimed is:

1. A galloping motion disruptor for a conductor, the galloping motion disruptor comprising: a first disruptor rod and a second disruptor rod, each of the first and second disruptor rods comprising a first end portion, a second end portion, and a mid-section between the first end portion and the second end portion, the first end portion comprising a helical gripping section, the second end portion comprising a hook section, wherein the hook sections of the first and second disruptor rods are connectable to each other, and an extension rod comprising a first end portion and a second end portion each comprising a hook section, wherein the hook sections of the first and second disruptor rods are indirectly connected together by the first end portion hook section of the extension rod connected to the hook section of the first disruptor rod and the second end portion hook section of the extension rod connected to the hook section of the second disruptor rod, and wherein the first disruptor rod, the second disruptor rod, and the extension rod are attachable to the conductor to disrupt galloping motion.

2. The galloping motion disruptor of claim 1 , wherein the first disruptor rod and the second disruptor rods are each an extruded preform.

3. The galloping motion disruptor of claim 1 , wherein the first disruptor rod and the second disruptor rod are each formed from a plastic.

4. The galloping motion disruptor of claim 1 , wherein the first disruptor rod and the second disruptor rod are each formed from a polyvinyl chloride.

5. The galloping motion disruptor of claim 1 , wherein the first disruptor rod and the second disruptor rod are each a generally solid rod.

6. The galloping motion disruptor of claim 1 , wherein the first disruptor rod and the second disruptor rod each have a maximum outer diameter of between 0.4 inches and 1.5 inches.

7. The galloping motion disruptor of claim 1 , wherein the hook section of each of the first disruptor rod and the second disruptor rod comprises a curved portion, an inwardly-extending linear portion, and an outwardly-extending linear portion.

8. The galloping motion disruptor of claim 1 , wherein the hook section of each of the first disruptor rod and the second disruptor rod defines a gap, and wherein a minimum width of the gap is less than a maximum diameter of the one of the first disruptor rod or the second disruptor rod.

9. A method for reducing conductor galloping, the method comprising: attaching a helical gripping section of a first disruptor rod on a conductor, the first disruptor rod comprising a first end portion, a second end portion, and a mid-section between the first end portion and the second end portion, the first end portion comprising the helical gripping section, the second end portion comprising a hook section; attaching a helical gripping section of a second disruptor rod on the conductor, the second disruptor rod comprising a first end portion, a second end portion, and a mid-section between the first end portion and the second end portion, the first end portion comprising the helical gripping section, the second end portion comprising a hook section; connecting the hook sections of the first and second disruptor rods together; wrapping the mid-sections of the first and second disruptor rods around the conductor, and wrapping a mid-section of an extension rod around the conductor, the extension rod comprising a first end portion, a second end portion, and the mid-section between the first end portion and the second end portion, the first end portion and the second end portion each comprising a hook section, wherein the hook sections of the first and second disruptor rods are indirectly connected together by directly connecting the first end portion hook section of the extension rod to the hook section of the first disruptor rod and directly connecting the second end portion hook section of the extension rod to the hook section of the second disruptor rod.

10. The method of claim 9 , wherein a maximum inner diameter defined by the helical gripping section of the first disruptor rod and a maximum inner diameter defined by the helical gripping section of the second disruptor rod are each less than a maximum outer diameter of the conductor.

11. The method of claim 9 , wherein a maximum pitch of the mid-section of the first disruptor rod and a maximum pitch of the mid-section of second disruptor rod are each greater than a maximum pitch of the helical gripping section of the first disruptor rod and a maximum pitch of the helical gripping section of the second disruptor rod.

12. The method of claim 9 , wherein the first disruptor rod and the second disruptor rods are each an extruded preform.

13. The method of claim 9 , wherein the first disruptor rod and the second disruptor rod are each a generally solid rod.

14. The method of claim 9 , wherein the first disruptor rod and the second disruptor rod each have a maximum outer diameter of between 0.4 inches and 1.5 inches.

15. The method of claim 9 , wherein the hook section of each of the first disruptor rod and the second disruptor rod comprises a curved portion, an inwardly-extending linear portion, and an outwardly-extending linear portion.

16. The method of claim 9 , wherein the hook section of each of the first disruptor rod and the second disruptor rod defines a gap, and wherein a minimum width of the gap is less than a maximum diameter of the one of the first disruptor rod or the second disruptor rod.

17. The method of claim 9 , wherein the hook sections of the first and second disruptor rods are directly connected together.
