The present invention relates to a jump wire support for power distribution lines. The jump wire support includes: a first connection support installed on a side of a column by a rotary connection unit in a rotatable manner； a first insulator installed on the first connection support； a first power distribution line connected to the first support by the rotary connection unit in a rotatable manner； a second connection support installed on the other side of the column by the rotary connection unit in a rotatable manner； a second insulator installed on the second connection support； a second distribution line connected to the second connection support by the rotary connection unit in a rotatable manner； a jump wire which connects the rotary connection units individually connected to the first and second power distribution lines to electrically connect the first and second power distribution lines to connect the first and second power distribution lines by using the rotary connection units in a rotatable manner； a mount unit connected to the column and the jump wire to be installed on the column in a rotatable manner； a mounting bracket installed on the mount unit； and a rotary driving unit which is installed on a driving groove unit formed on the center part of the column, is connected to the jump wire, and senses the birds sitting on the mount, mount bracket, jump wire, first insulator, second insulator, first connection support, and second connection support, and prevents the birds from sitting on the jump wire by rotating the jump wire from one side to the other side of the column or vice versa.본 발명은, 지주의 일측에 회전연결부에 의해 회전 가능하게 설치되는 제1연결대； 상기 제1연결대에 설치되는 제1애자； 상기 제1연결대에 회전접속부에 의해 회전 가능하게 연결되는 제1배전선； 지주의 타측에 회전연결부에 의해 회전 가능하게 설치되는 제2연결대； 상기 제2연결대에 설치되는 제2애자； 상기 제2연결대에 상기 회전접속부에 의해 회전 가능하게 연결되는 제2배전선； 상기 제1배전선과 상기 제2배전선을 전기적으로 연결하도록 상기 제1배전선에 연결되는 상기 회전접속부와, 상기 제2배전선에 연결되는 상기 회전접속부를 전기적으로 연결하고, 상기 회전접속부에 의해 상기 제1배전선 및 상기 제2배전선에 회전 가능하게 연결되는 점프선； 상기 지주와 상기 점프선을 연결하고, 상
