Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a long-rod support insulator from falling down and, further, prevent jumper wires from coming abnormally close to a tower main part even if a highest grade earthquake happens. SOLUTION: A long-rod support insulator which is used for preventing jumper wires which link main lines pulled by a pair of tension devices from vibration are attached to an arm 21 provided on a tower. The end metal fitting 43 of long rod support insulator is fixed to the arm 21 with an attaching member 5 therebetween. The attaching member 5 is composed of a ceramic cylindrical member 51 having a small diameter part 52 and arm side and end side metal fittings 53 and 54 which are fixed to both the ends of the ceramic cylindrical member 51. A plurality of metal chains 6 which are auxiliary members are spanned between the arm side metal fitting 53 and the end side metal fitting 54.
