WEDGE-SHAPED ANCHOR CLAMP AND INSULATOR DEVICE REPAIR METHOD USING WEDGE-SHAPED ANCHOR CLAMP

To provide a wedge-shaped anchor clamp for replacement and an insulator device repair method using the wedge-shaped anchor clamp for replacement, which can realize a labor saving of repair work of an insulator device and can improve the safety of the repair work of the insulator device.SOLUTION: A wedge-shaped anchor clamp, which is for replacement of an existing wedge-shaped anchor clamp, comprises: a pair of wedges for grasping a main electric cable suspended in a tensioned state; a clamp body into which the pair of wedges is inserted; a joint plate, one end of which is connected to the clamp body, and the other end of which is connected to a mating metal fitting; and a jumper metal fitting for fixing a jumper-side cable, one end of which is connected to the wedge. The length of the joint plate is between 600 mm and 1100 mm. The length of the jumper metal fitting is between 450 mm and 900 mm. The curvature radius of the jumper metal fitting in the lengthwise direction is between 470 mm and 1000 mm.SELECTED DRAWING: Figure 1 【課題】碍子装置の改修工事を省力化でき、また、碍子装置の改修工事の安全性を向上させることができる、取替用楔形引き留めクランプ及び取替用楔形引き留めクランプを用いた碍子装置改修方法を提供する。【解決手段】張架されている電線本線を把持する一対の楔と、前記一対の楔が挿入されたクランプ本体と、一端が前記クランプ本体と連結され、他端が相手金具と連結される連結板と、一端が前記楔と連結された、ジャンパ側電線を固定するジャンパ金具と、を備え、前記連結板の長さが、６００ｍｍ以上１１００ｍｍ以下であり、前記ジャンパ金具の長さが、４５０ｍｍ以上９００ｍｍ以下、前記ジャンパ金具の長さ方向の曲率半径が４７０ｍｍ以上１０００ｍｍ以下であり、既設楔形引き留めクランプの取替用である、楔形引き留めクランプ。【選択図】図１
