The present invention relates to a device for preventing sag of a jump line in an overhead transmission line. A buffer device (100) is installed between jump lines (J). A left jump line (J) is fixed to the buffer device (100) through a left jump line fixing tool (200). A right jump line (J) is fixed to the buffer device (100) through a right jump line fixing tool (300). In this case, the buffer device (100) protects the respective jump lines (J) from external force by providing buffer force to the left jump line (J) and the right jump line (J) through a left spring (160), a right spring (170), and a center spring (180). Further, the buffer device (100) includes a lower rotation ball (120) and an upper rotation ball (130). The lower rotation ball (120) and the upper rotation ball (130) provide a buffer force for the movements of a left moving tool (140) and a right moving tool (150) located inside the buffer device (100) so that the respective jump lines (J) are further protected from the external force. Accordingly, the present invention may prevent a sag of the jump lines (J) due to the external force and sag of a connection portion between the jump lines (J) and an overhead transmission line by buffering the external force applied to the jump lines (J). |
