<p>PROBLEM TO BE SOLVED: To prevent the damage of an interphase spacer, by so configuring the interphase spacer of multi-coductor aerial transmission lines that the respective multi-conductors of the horizontal opposite phases of different lines are made movable in the directions of the transmission lines by they do not rotate using their central position as an axis. SOLUTION: In tow-conductor transmission lines comprising an interphase spacer 1 interposed in an attached way between respective multi-conductors (A1 , A2 ) and (B1 , B2 ) of horizontal opposite phases, the respective multi- conductors can not rotate using as an axis the middle portion between the respective multi-conductors while they can be moved respectively in the directions of the transmission lines via respective I-metal fittings 13 and lateral U-shaped coupling metal fittings 21. Also, insulation body portions 10 of the interphase spacer 1 are placed under the plane including the respective conductors A1 , A2 , B1 , B2 of the horizontal opposite phases, and thereby, the respective conductors do not collide against the insulation body portions 10 even in the case of their movements, and do not damage the insulation body portions 10.</p> |
