<p><P>PROBLEM TO BE SOLVED: To provide a jumper device excellent in workability, easiness in construction and reduction in construction time when forming or adding a jumper part on a pipe body in a jumper device of a pipe system. <P>SOLUTION: In the jumper device arranged on a steel tower for stringing and connecting an overhead wire, the jumper device has a conductive pipe body arranged in the transverse direction as a jumper conductor at an intermediate part. The pipe body is structured with a first pipe body and a second one divided into two, being separated at the center. The first pipe body has a terminal connection part at the end of the second pipe body side. The second pipe body has a terminal connection part at the end of the first pipe body side, and an intermediate connection member is arranged between the first pipe body and the second one. The intermediate connection member has first and second connection end parts at both ends. The terminal connection part of the first pipe body is conductively connected to the first connection end part of the intermediate connection member, while the terminal connection part of the second pipe body is conductively connected to the second connection end part of the intermediate connection member. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
