그리고, 가공배전선로의 본선에서 변압기(주상 변압기)로 전력을 분기하는 경우, 본선과 분기선이 분기 슬리브를 매개로 접속된다. And, when power is branched from the main line of the overhead distribution line to the transformer (pole-phase transformer), the main line and the branch line are connected via a branch sleeve.

이때, 분기선은 변압기로 향할 시, 변압기의 배치 위치가 분기 슬리브에서 멀면 분기선이 늘어질 수 있어, 바람 등에 의해 분기선에 외력이 가해질 경우 변압기로의 안정적 전력 공급에 어려움이 있었다.At this time, when the branch line is directed to the transformer, if the arrangement position of the transformer is far from the branch sleeve, the branch line may sag.

또한, 본선과 분기선은 분기 슬리브를 매개로 횡방향으로 배치되게 접속되고, 분기 슬리브를 가압하여 본선과 분기선을 분리 슬리브에 고정한다.In addition, the main line and the branch line are connected to be disposed in the transverse direction through the branch sleeve, and the branch sleeve is pressed to fix the main wire and the branch line to the separation sleeve.

그러나, 종래에는 본선을 분기 슬리브에 가압 고정하더라도 외력에 의해 분기 슬리브가 벌어지면서 본선과 분기 슬리브의 접속이 정상적으로 이루어지지 않는 문제점이 있었다. However, in the related art, there is a problem in that even if the main line is pressed and fixed to the branch sleeve, the branch sleeve is opened by an external force and the connection between the main line and the branch sleeve is not normally made.
