Embodiment
As depicted in figs. 1 and 2, the power transmission line spacer of the anti-subspan oscillation of quadripartion formula described in the utility model, comprise quadrilateral frame 1 and wire clamp, wire clamp comprises two long wire clamps 2 and two short-term folders 3, long wire clamp 2 and short-term folder 3 are disposed alternately on four drift angles of quadrilateral frame 1 successively, the front end of four drift angles difference connecting clamps of quadrilateral frame 1, the rear end of wire clamp is provided with folder hole, and folder hole inwall is provided with rubber blanket 4; The center line of two wire clamps that quadrilateral frame 1 diagonal angle is arranged is positioned on the cornerwise extended line corresponding to this diagonal angle.The utility model utilizes the long wire clamp 2 that is arranged alternately and short-term folder 3, can increase and be separately fixed at the spacing that long wire clamp 2 and short-term press from both sides the bundle conductor of 3 folder hole inside.
In the utility model, the folder hole line of centres 5 of adjacent long wire clamp 2 and short-term folder 3 therewith angle α formed by the sideline 6 of rectangular frame that is connected of long wire clamp 2 and short-term folder 3 is greater than 0 °.By arranging the size of angle α, the relative position of adjacent long wire clamp 2 and the wire of short-term folder clamped by 3 can be changed, and angle α is larger, the distance of adjacent long wire clamp 2 and the wire of short-term folder clamped by 3 is far away, accordingly, the wake effect that the sub-conductor being in leeward side is subject to the sub-conductor being in windward side is less, more subspan oscillation is less likely to occur.
