FIXING STRUCTURE OF LONG ROD SUPPORT INSULATOR

摘要

PROBLEM TO BE SOLVED: To provide the fixing structure of a long rod support insulator in which a long rod support insulator is not damaged even by a large vibration capable of keeping function even after a large vibration occurs.

SOLUTION: A fitting plate 20 fixed to the arm of a power transmission tower 12 and an end plate 18 on the power transmission tower side of a long rod support insulator 11 are fixed to the bolt hole 19 of the end plate 18 and a bolt hole 21 of the fitting plate 20 using a nut 27 by penetrating a bolt 22. The bolt 22 is loosely fitted to the bolt holes 19 and 21. The bolt 22 is interposed with an elastic member 24 (24A and 24B). The elastic member 24 (24A and 24B) is fastened with the nut 27 screwed on the bolt 22 while clamped under a prescribed compression force.
