The present disclosure is related to providing an overhead transmission line spacer which can suppress galloping caused by strong wind in the three-conductor transmission line formed of three overhead transmission lines. An overhead transmission line spacer comprising: three clamps configured to individually hold three overhead transmission lines; and a frame body including support members and a frame portion, and configured to maintain separations between the three overhead transmission lines via the three clamps, the clamps being attached to the support members, and the frame portion maintaining separations between the support members, wherein two out of the three clamps are movable clamps, each of which is configured to hold one of the overhead transmission lines in a rotatable manner about the one of the overhead transmission lines, and one out of the three clamps is a fixed clamp configured to hold one of the overhead transmission lines without allowing rotation.

Overhead transmission line spacer

An overhead line damper capable of suppressing a lift force that an overhead line receives due to wind is provided. A damperfor an overhead line that is provided at an overhead line Lincludes a clamping mechanism (a pair of hinge piecesand) that is fitted to an outer circumferential surface of the overhead line L, and a rotary memberwith a lower part attached to weightsand, and an upper part rotatably attached to the clamping mechanism, and the clamping mechanism has a regulation part (an opening part) that regulates a rotation range of the rotary memberso that the weightsandrotate within an angle range from &#xb1;20 degrees to &#xb1;40 degrees inclusive in a vertical direction.
