<p><P>PROBLEM TO BE SOLVED: To provide a high-voltage pulling-down line supporting hardware which can be safely and easily mounted on high-voltage arm metals by making the arms into a structure which allows the arms to be readily hung on the high-voltage arm metals, and is prevented from being fallen off from the high-voltage arm metals, even if the mounting section of the nut of a high-voltage insulator loosens. <P>SOLUTION: The high-voltage pulling-down line supporting hardware comprises downward substantially U-shaped crossarms 2 to be fitted axially to the high-voltage arm metals 52 from the end part of the high-voltage arm metals 52; supporting arms 3 connected so that the supporting arms project in the axial direction of the high-voltage arm metals 52 from both sides of the crossarms 2 respectively; a first guide body 5 and a second guide body 6 provided at the rear end part of the supporting arms 3 and projecting respectively upward at a substantially same interval of the lateral width of the high-voltage arm metals 52 to constitute the rear arms 4; a bolt 7 with a nut provided at the upper part of the first guide 5 and pivotally supported in such a way capable of falling aside on the second guide body 6 side; and an engaging groove 8 formed in the upper part of the second guide body 6 and engaged with the bolt 7 with the nut. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
