<p><P>PROBLEM TO BE SOLVED: To provide a method for sharing an upper branch line that can easily and safely lay the branch line that is difficult in laying for the reason that negotiation for the procurement of a site is troublesome, there are restrictions in terms of a space, and the appearance of an environment might be impaired; and to provide a common metal fitting of the upper branch line and a tension adjuster of the upper branch line. <P>SOLUTION: When anchoring a plurality of cables 2A to 2C installed to an electric pole 1, the upper branch lines 3A to 3C are aggregated into one piece by concentrating tensions created by the cables 2A to 2C with respect to the upper branch lines that are necessary for the cables 2A to 2C in the same number of pieces of the cables. An imbalanced load to the electric pole 1 that shares the upper branches is dispersed by making tensional directions caused by the upper branches coincide with one another. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
