<p>PURPOSE:To surely prevent a grounded trouble in a supporting member for a feeder due to birds, etc. CONSTITUTION:A supporting frame 1 consisting of a longitudinal pipe 2 and transverse pipes 3 and 4 is fixed on a scaffolding supporting a trolley wire. A feeder 7 for supplying electric power to the trolley wire is suspension- supported through a supporting insulator 6 at the top edge of the transverse pipe 3 of the supporting frame 1. On the longitudinal pipe 2 and the transverse pipe 4, perches 12 and 14 are installed through an insulator 8 so as to be positioned between the longitudinal pipe 2, transverse pipe 4, and the feeder 7. A perch 13 is installed through the insulator 8 on the transverse pipe 3 so as to be positioned over the transverse pipe 3.</p> |
