Abstract

A vibration resistant cable having a first conductor and a second conductor. The second conductor may be twisted around the first conductor at a lay length configured to cause a locking force between the first conductor and the second conductor. The locking force may be configured to prevent relative movement of the first conductor and the second conductor that may result in bags in the vibration resistant cable. The lay length may be predetermined or may vary a predetermined amount per unit of length of the vibration resistant cable. The lay length may be c1d+c2, where d may be the diameter of the first conductor and the second conductor and c1 and c2 may be constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable.

Claims (31)

1. A vibration resistant cable comprising:

a first conductor; and

a second conductor twisted around the first conductor at a lay length configured to cause a locking force between the first conductor and the second conductor configured to prevent relative movement of the first conductor and the second conductor that would result in bags in the vibration resistant cable.

2. The vibration resistant cable of claim 1 , wherein the lay length is predetermined.

3. The vibration resistant cable of claim 2 , wherein the lay length is one of the following: equal to 9 ft. and less than 9 ft.

4. The vibration resistant cable of claim 2 , wherein the lay length is between 6 ft. and 3 ft.

5. The vibration resistant cable of claim 2 , wherein the lay length is between 6 ft. and 9 ft.

6. The vibration resistant cable of claim 2 , wherein the lay length is 3 ft.+/−10%.

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

8. The vibration resistant cable of claim 7 , wherein the lay length is varying between 3 ft. and 6 ft.

9. The vibration resistant cable of claim 7 , wherein the varying lay length comprises the lay length varying a predetermined amount per unit of length of the vibration resistant cable.

10. The vibration resistant cable of claim 1 , wherein the lay length is further configured to reduce a drag force when wind blows across the vibration resistant cable.

11. The vibration resistant cable of claim 1 , wherein the lay length is further configured to reduce a drag force when wind blows across the vibration resistant cable when a component of the wind is in a perpendicular direction to an axis of the vibration resistant cable.

12. The vibration resistant cable of claim 1 , wherein the lay length is represented by:

lay length=c 1 d+c 2 , where d is the diameter of the first conductor and the second conductor and c 1 and c 2 are constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable.

13. The vibration resistant cable of claim 1 , wherein the lay length is represented by:

lay length=c 1 d+c 2 , where d is the diameter of the first conductor and the second conductor and c 1 and c 2 are constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable, wherein the Aeolian vibration dampening is provided when a power line using the vibration resistant cable is built to any one of the following National Electric Safety Code (NESC) standards: heavy loading district minimum design conditions, medium load district minimum design conditions, and light load district minimum design conditions.

14. A vibration resistant cable comprising:

a first conductor; and

a second conductor twisted around the first conductor at a lay length configured to cause a locking force between the first conductor and the second conductor configured to prevent relative movement of the first conductor and the second conductor that would result in bags in the vibration resistant cable, wherein the lay length is varying between 3 ft. and 6 ft. and wherein the lay length is configured to reduce a drag force when wind blows across the vibration resistant cable.

15. The vibration resistant cable of claim 14 , wherein the lay length is configured to reduce the drag force when a component of the wind is in a perpendicular direction to an axis of the vibration resistant cable.

16. The vibration resistant cable of claim 14 , wherein the lay length is represented by:

lay length=c 1 d+c 2 , where d is the diameter of the first conductor and the second conductor and c 1 and c 2 are constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable.

17. The vibration resistant cable of claim 14 , wherein the lay length is represented by:

lay length=c 1 d+c 2 , where d is the diameter of the first conductor and the second conductor and c 1 and c 2 are constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable, wherein the Aeolian vibration dampening is provided when a power line using the vibration resistant cable is built to any one of the following National Electric Safety Code (NESC) standards: heavy loading district minimum design conditions, medium load district minimum design conditions, and light load district minimum design conditions.

18. A vibration resistant cable comprising:

a first conductor; and

a second conductor twisted around the first conductor at a lay length configured to cause a locking force between the first conductor and the second conductor configured to prevent relative movement of the first conductor and the second conductor that would result in bags in the vibration resistant cable, wherein the lay length is predetermined and is one of the following: equal to 9 ft. and less than 9 ft., wherein the lay length is represented by:

lay length=c 1 d+c 2 , where d is the diameter of the first conductor and the second conductor and c 1 and c 2 are constants configured to obtain the locking force to eliminate bags in the vibration resistant cable and provide Aeolian vibration dampening in the vibration resistant cable.

19. The vibration resistant cable of claim 18 , wherein the lay length is further configured to reduce a drag force when wind blows across the vibration resistant cable.

20. The vibration resistant cable of claim 18 , wherein the lay length is further configured to reduce a drag force when wind blows across the vibration resistant cable when a component of the wind is in a perpendicular direction to an axis of the vibration resistant cable.
