SUPPORTING METHOD AND DEVICE FOR JUMPER PART OF OPGW

摘要

PURPOSE:To provide a supporting method and supporting devices for jumper parts of OPGWs which make relaxation adjustment possible after clamping. CONSTITUTION:An OPGW 1 has a jumper part 6 in the periphery of a steel tower. And in the case of adjusting the degree of relaxation of the OPGW supported by the steel tower in the air, the jumper part 6 is made beforehand in a state of being loosened into a curved shape, and a clamp part 7 is formed in its center part. At the time of degree of relaxation adjustment, the sending- out or taking-in of the OPGW 1 is compensated by the extension or shrinkage of the jumper part 6, and the clamp part 7 is held by the steel tower in a freely linearly-movable or rotatable way, and the shape change of the jumper part by the extension or shrinkage caused by relaxation adjustment is regulated.
