The present invention relates to a drooping preventing device for an overhead distribution line which prevents an overhead distribution line installed on an electric pole from drooping. The drooping preventing device for an overhead distribution line according to an embodiment of the present invention comprises : a drooping prevention tube which includes a plurality of tube unit entities for preventing the distribution line from drooping, wherein the tube unit entities are inserted into the distribution line to be supported by one another; and a line pulling tool which includes a rotating portion which rotates the drooping prevention tube such that the drooping prevention tube is vertically inverted, and a rotating pulling member which pulls a drooped distribution line by lifting the distribution line such that the drooping prevention tube easily rotates, when the drooping prevention tube is rotated by the rotating portion. The tube unit entity includes a supporting plate portion which protrudes from an upper portion of the distribution line in a length direction and is supported across top portions of adjacent tube unit entities, a pin coupling portion which protrudes from both sides of a center portion of the tube unit entity in a protruding direction of the supporting plate portion, and a coupling pin portion which protrudes from both sides to be opposite to the pin coupling portion (213), wherein the pin coupling portion of the adjacent tube unit entity is coupled with the coupling pin portion to rotate. The rotating portion includes a rotating disk having an insertion hole, to which the pin coupling portion and the supporting plate portion are inserted, and sawteeth formed on a circumference of the rotating disk, and a handle which is engaged with the sawteeth of the rotating disk to rotate the rotating disk. Therefore, the drooping preventing device for an overhead distribution line can be easily installed on the distribution line, and installation costs can be reduced.COPYRIGHT KIPO 2016
