Abstract
A device for suppressing wind induced motions in aerial cables and a method of installing the same. The device comprises a cylindrical rod of substantial length having a generally straight center section terminating in helically configured cable gripping sections. Adjacent one end is a non-gripping support helix. The support helix functions to provide support to one end of the device while the device is slid to a position on the cable where the helically configured gripping section at the opposite end can be wrapped to the aerial cable.
Claims12
A device for dampening wind induced vibrations in aerial cables comprising:
- an elongated rod having a generally straight midsection terminating in helically configured cable gripping sections sized so as to tightly grip the aerial cable on which the device is to be used, and a support helix associated with at least one of said gripping sections, said support helix comprising at least one complete spiral with an open inner diameter greater than the inner diameter of the helically configured gripping sections and at least approximately as great as the diameter of the cable on which the device is to be used.
A method of installing on aerial cables a vibration dampener of the type comprising an elongated rod with a generally straight midsection terminating at first and second ends in cable gripping helical sections and having at least one non-gripping support helix adjacent the first end, said method comprising the steps of:
- (a) at a first location adjacent the cable, wrapping said support helix about the cable;
- (b) while remaining generally at said first location, sliding said rod along said cable to bring said second end generally to the first location;
- (c) wrapping the cable gripping helical portion at the second end into gripping relationship with said cable;
- (d) wrapping the straight midsection of the rod around said cable and;
- thereafter,
- (e) applying the cable gripping helical portion at the first end to said cable.
