<p>PURPOSE:To sharply reduce the working time and sufficiently secure the safety of the title method by adopting a straightly-pulled aerial wire anchoring method and device and changing the aerial wire of a straight-pull assembling system to the aerial wire of an anchor assembling system. CONSTITUTION:An anchoring device 8 is hang up above a D-shaped arm 7 without allowing an aerial wire W to come off an anchor insulator by a straight-pull assembling system and the upper end of the arm 7 is trued to a level immediately below a clearance A formed between a left and right arms 8a and 8a. Then the hang up anchoring device 8 is lowered to a level immediately above the arm 7 and fixed to the arm 7 by vertically putting the arms 8a and 8a along both sides of the arm 7 and inserting a bolt 9 into a bolt-hole S and another bolt-hole P bored through the arm 7 so as to meet the bolt-hole S after the holes S and P are made to meet each other. Thereafter, the three- phase aerial wire W is clamped by means of anchoring clamps 8e, 8e, and 8e and cut off at the left-and right-side positions X and X of each straight-pull insulator 10. After cutting the wire W, the insulators 10 are removed from the D-shaped arm 7.</p> |
