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.
