Abstract

Vibration resistant cables containing a first conductor and a second conductor, each having a diameter d, are disclosed. The second conductor is twisted around the first conductor at a particular lay length to eliminate bagging of the vibration resistant cable.

Claims (12)

1. A vibration resistant cable comprising:

a first conductor having a diameter d; and

a second conductor having the diameter d, the second conductor twisted around the first conductor at a lay length between 3 feet and 6 feet to eliminate bagging of the vibration resistant cable during installation.

2. The vibration resistant cable of claim 1 , wherein the lay length is further configured to cause a locking force between the first conductor and the second conductor to reduce relative movement.

3. The vibration resistant cable of claim 1 , wherein the lay length is further configured to allow some relative movement between the first conductor and the second conductor to provide Aeolian vibration dampening in the vibration resistant cable.

4. The vibration resistant cable of claim 1 , wherein the first conductor and the second conductor each comprise a respective plurality of strands.

5. The vibration resistant cable of claim 4 , wherein the first conductor and the second conductor each comprise seven strands.

6. The vibration resistant cable of claim 4 , wherein the first conductor and the second conductor each comprise six aluminum strands surrounding a steel strand.

7. The vibration resistant cable of claim 1 , wherein an optimum lay length is a function of the diameter d.

8. The vibration resistant cable of claim 1 , wherein an optimum lay length is determined by the equation, c 1 d+c 2 , wherein c 1 and c 2 are constants configured to obtain a locking force to eliminate bagging in the vibration resistant cable and to provide Aeolian vibration dampening in the vibration resistant cable.

9. The vibration resistant cable of claim 1 , wherein the vibration resistant cable is not under tension in a power line.

10. The vibration resistant cable of claim 1 , wherein the lay length is varying.
