Zusammenfassung: | PURPOSE:To obtain an interphase spacer by which the whole of the interphase spacer can be inspected precisely in an inspection, which can ensure the insulation between transmission lines for a long period, which saves the labor of an operation in the inspection and which enhances the efficiency of the operation. CONSTITUTION:One end of a first interphase spacer 1 is constituted of a first long trunk insulator 8 and of a second long trunk insulator 9, and the other end is constituted of a third long trunk insulator 10 and of a fourth long trunk insulator 11. A cylindrical coupling pipe 15 is constituted so as to be coupled between the long trunk insulators 9, 10. Foot-placing rods 18 are fixed by means of nuts in such a way that their screw parts, on one side, are tightened to trapezoidal metal fittings at the coupling pipe 17. The foot-placing rods 18 are installed at prescribed intervals, and an inspection operator places his feet. In addition, when both end parts of the interphase spacer 1 are constituted of polymer insulators, the operator cannot grip them. Consequently, a ladder by which the operator can go up and down is installed side by side. |
