OVERHEAD DISTRIBUTION LINE INSULATION COVER

PROBLEM TO BE SOLVED: To provide an overhead distribution line insulation cover which can be attached/detached without using multiple kinds of indirect hot-line tools and is prevented from being opened unexpectedly.SOLUTION: An overhead distribution line insulation cover 1 comprises: an inner cover 2 being capable of accommodating a non-insulation part of a distribution line in an inner diameter part 21 and including a slit 24 that becomes an entrance/exit to/from the inner diameter part 21 through both end faces 22 and in an axial direction of a peripheral side face 23; and an outer cover 3 being capable of accommodating the inner cover 2 in an inner diameter part 31 and including a slit 34 which becomes an entrance/exit to/from the inner diameter part 31 through both end faces 32 and in an axial direction of a peripheral side face 33. The inner cover 2 that is accommodated in the outer cover 3 is mounted to an outer periphery of the distribution line and the outer cover 3 is rotated around the inner cover 2, thereby closing the slits 24 and 34.SELECTED DRAWING: Figure 2 【課題】複数種類の間接活線工具を使用せずに取り付けおよび取り外しを行うことができ、かつ不用意に開いてしまうことのない架空配電線用絶縁カバーを提供する。【解決手段】架空配電線用絶縁カバー１は、内径部２１に配電線の非絶縁部が収容可能とされ、両端面２２と周側面２３の軸方向とに沿うように内径部２１への出入り口となるスリット２４が設けられた内側カバー２と、内径部３１に内側カバー２が収容可能とされ、両端面３２と周側面３３の軸方向とに沿うように内径部３１への出入り口となるスリット３４が設けられた外側カバー３とを備える。外側カバー３に収容された内側カバー２配電線の外周に装着し、外側カバー３を内側カバー２の周りで回転することで、スリット２４、３４を閉じる。【選択図】図２
