<p>PURPOSE:To suppress vibration such as galloping without causing buckling by forming a polymer insulator so that it is bendable in a plane including conductors of horizontally opposing phases and shifting the fixing position of conductor grip metal in the direction of the line thereby following up the motion of the conductor somewhat freely. CONSTITUTION:A polymer insulator 4 comprises a horizontal distance adjusting metal 5 in the center and a polymer insulator body 6, a link 7 and a conductor grip metal 8 are coupled sequentially on the opposite sides. Since coupling pin of each member directs in the vertical direction, it is bendable in a plane including conductors 2A, 3A. Furthermore, fixing position of the conductor grip metal 8 in the polymer insulator 4 is shifted in the direction of the line. Consequently, interference between the coupled conductors of horizontally opposing phase can be promoted resulting in effective suppression of large amplitude vibration.</p> |
