To provide a trolley wire with a built-in abrasion detection line which can restrain replacement life from deteriorating when overhead power line is provided in a section where inclined wear occurs.SOLUTION: A trolley wire 1 comprises: a trolley wire body 10 which includes two holes 14a, 14b for abrasion detection line which are provided on both sides of center line 18 in its inside; and two abrasion detection lines 20 which are stored in the two holes 14a, 14b for abrasion detection line. In cross section of a radial direction of the trolley wire body 10, the trolley wire is configured so that common circumscription line 15 of upper side of contour of the two holes 14a, 14b for abrasion detection line is larger than 1° from a width direction of the trolley wire body 10 and inclines at angle of 13°or less.SELECTED DRAWING: Figure 1
【課題】摩耗検知線を内蔵するトロリ線であって、傾斜摩耗が生じる区間に架線された場合の張替寿命の低下を抑えることができるトロリ線を提供する。【解決手段】中心線18の両側に設けられた2つの摩耗検知線用孔14a、14bを内部に有するトロリ線本体10と、前記2つの摩耗検知線用孔14a、14bに収容された2本の摩耗検知線20と、を備え、前記トロリ線本体10の径方向の断面において、前記2つの摩耗検知線用孔14a、14bの輪郭の上側の共通外接線15が、前記トロリ線本体10の幅方向から1°より大きく、13°以下の角度で傾いている、トロリ線1を提供する。【選択図】図1
