Method and apparatus for provision of temporary conductor tension support in transmission or distribution circuits
A conductor supporting assembly includes a pair of yokes having a pair of cables extending therebetween in spaced parallel array. Actuators tension the cables so as to selectively draw the yokes toward each other along the cables. Grips cooperate with yokes for mounting the yokes in spaced apart array to and along a conductor segment of a conductor to be serviced so as to extend the conductor segment along and substantially medially between the yokes. The drawing of the yokes toward each other thereby de-tensions the conductor segment to allow for repair or service.
1. A conductor supporting assembly comprising:
an opposed-facing pair of first and second tension supports having a parallel pair of flexible first and second elongate members extending therebetween in spaced parallel array, a means for tensioning said first and second elongate members so as to selectively draw said first and second tension supports toward each other, first and second conductor mounts cooperating with said first and second tension supports for mounting said first and second tension supports in spaced apart array to and along a conductor segment of a conductor to be serviced so as to extend the conductor segment along and substantially medially between said first and second elongate members, whereby said drawing of said first and second tension supports toward each other de-tensions the conductor segment to allow for the service, wherein said tension supports are yoke assemblies, and wherein each yoke assembly of said yoke assemblies include a rigid spreader element extending orthogonally between said elongate members.
2. The assembly of claim 1 wherein said each yoke assembly is a rigid yoke.
3. The assembly of claim 2 wherein said each yoke assembly includes a flexible sling extending from a corresponding said spreader element.
4. The assembly of claim 1 wherein said each spreader element is adjustable along its length so as to selectively adjust a spacing between said elongate members.
5. The assembly of claim 1 wherein said yoke assemblies are substantially planar.
6. The assembly of claim 1 further comprising at least one elongate insulated tool mountable to a corresponding tension support so as to depend downwardly therefrom and stabilize the mounting of said corresponding tension support onto the conductor segment.
7. The assembly of claim 6 wherein said tension supports are yoke assemblies each including a rigid spreader element, and wherein said tool mounts underneath, in cooperation with, said spreader element.
8. The assembly of claim 1 further comprising at least one insulator mounted in cooperation with and between said elongate members and said tension supports.
9. A method of supporting a conductor comprising the steps of:
a) providing an opposed-facing pair of first and second tension supports having a parallel pair of flexible first and second elongate members extending therebetween in spaced parallel array,
b) providing first and second conductor mounts cooperating with said first and second tension supports and mounting said first and second tension supports in spaced apart array to and along a conductor segment of a conductor to be serviced so as to extend the conductor segment along and substantially medially between said first and second elongate members,
c) providing a means for tensioning said first and second elongate members and selectively drawing said first and second tension supports toward each other, so as to de-tension the conductor segment to allow for the service,
wherein said tension supports are yoke assemblies, and wherein each yoke of said yoke assemblies include a rigid spreader element extending orthogonally between said elongate members.
10. The method of claim 9 wherein said each yoke assembly is a rigid yoke.
11. The method of claim 10 wherein said each yoke assembly includes a flexible sling extending from a corresponding said spreader element.
12. The method of claim 9 wherein said each spreader element is adjustable along its length so as to selectively adjust a spacing between said elongate members.
13. The method of claim 9 wherein said yoke assemblies are substantially planar.
14. The method of claim 9 further comprising at least one elongate insulated tool mountable to a corresponding tension support so as to depend downwardly therefrom and stabilize the mounting of said corresponding tension support onto the conductor segment.
15. The method of claim 14 wherein said tension supports are yoke assemblies each including a rigid spreader element, and wherein said tool mounts underneath, in cooperation with, said spreader element.
16. The method of claim 9 further comprising at least one insulator mounted in cooperation with and between said elongate members and said tension supports.
