The invention belongs to the fields of design, operation and overhauling of electric power system overhead transmission lines, in particular to a spring shock absorption type alternate waving-preventing spacing bar. The spacing bar is mainly used in electric transmission lines with the voltage classes of 66kV and more. According to the spring shock absorption type alternate waving-preventing spacing bar, a waving-preventing shock absorber is connected between two insulators of the alternate spacing bar through connecting fittings, and the two external ends of each insulator of the alternate spacing bar are connected with a line gland through the connecting fittings. The spring shock absorption type alternate waving-preventing spring bar can bear pressure or tension, a guiding rod can guide the alternate spacing bar to move in the axial direction of a spring, and a convex buckle baffle can prevent the damping spring from bearing excessive tension. The spacing bar can effectively improve stress distribution to the connecting positions of line glands after torque is increased after conducting wires are wrapped by ice, effectively restrain Aeolian vibration of lines and secondary span length vibration, provide the action of rapid releasing waving self-oscillation energy when waving occurs in a severe meteorological condition, and be significant in effect. The spring shock absorption type alternate waving-preventing spacing bar has the advantages of being simple and practical in structure, convenient to install, low in manufacturing cost and free of maintenance, and has wide application prospects.
