Zusammenfassung: | To provided an inexpensive tension device.SOLUTION: A tension device 1 for retaining four or more fictitious transmission lines E to a tower includes: an insulator ream 14 placed on the tower side; and the same predetermined number of jumper sockets 19 as the number of the fictitious transmission lines E, each of which is provided for each of the fictitious transmission lines E on the fictitious transmission line E side of the insulator ream 14 and holds one jumper line J. The predetermined number of jumper sockets 19 are arranged in a plurality of stages separated in the vertical direction, and a lower jumper socket 19D arranged in the lower stage of the predetermined number of jumper sockets 19 is obtained by arranging an upper jumper socket 19U, which is arranged above itself among the predetermined number of jumper sockets 19, at a position avoiding in the horizontal direction when viewed from the line extension direction of the fictitious transmission line E.SELECTED DRAWING: Figure 1
【課題】安価な耐張装置を提供する。【解決手段】4本以上の架空送電線Eを鉄塔に引き留めるための耐張装置1において、鉄塔側に配置された碍子連14と、碍子連14よりも架空送電線E側に架空送電線Eごとに設けられ、それぞれ1本のジャンパ線Jを保持する、架空送電線Eと同じ所定数のジャンパソケット19とを備え、所定数のジャンパソケット19は、上下方向に離間した複数段に分かれて配置されたものであり、所定数のジャンパソケット19のうち下段に配置された下段ジャンパソケット19Dは、架空送電線Eの延線方向から見て、所定数のジャンパソケット19のうち自身よりも上段に配置された上段ジャンパソケット19Uを水平方向に避けた位置に配置されたものである。【選択図】図1 |
