A spacer for transmission lines is provided to reduce external impact by an impact absorbing unit when the transmission lines are shaken by the external impact. A spacer for transmission lines includes a body(10), an impact absorption unit(20), and a clamping unit(30) coupled to a top portion of a rod(21). The clamping unit has a bottom member(35) with a plurality of first connection units(36). The clamping unit is formed to support a wire at a predetermined length. A top member(31) has a second connection unit(32) with a protrusion formed to be capable of being connected and disconnected with a plurality of hook holes of the first connection unit. A pair of guide grooves(13) are prepared at an inside surface of the boss to be extended downward along a lengthwise direction of the boss from a top portion at an to guide the rod in an elevation direction and a guide protrusion(23) is formed at the rod to move along the guide grooves. A groove supplies a moving path to allow air introduced from outside to move along inner surfaces of the top member and the bottom member. |
