The utility model relates to an insulator chain's shock attenuation conductor spacer, insulator chain includes the set -square, sets up the vertical setting in set -square both ends by insulator chain, win in succession and the link plate is connected on concatenating the II font insulator chain subassembly that forms and horizontal direction insulator chain's horizontally connect component, the horizontally connect component is the well font component that two T -connecting pieces are constituteed through the shock attenuation structrual joint, horizontally connect component both ends be equipped with with insulator chain swing joint's coupling assembling. The conductor spacer, through insulator chain between installing wholeness that conductor spacer improved insulator chain to dangling among the transmission line, solved between the suspension insulator wobbling problem each other, improve the security and the reliability of circuit.
