The utility model relates to a conductor spacer for insulator chain, insulator chain includes the set -square, sets up the vertical setting in set -square both ends concatenate the II font insulator chain subassembly that forms and horizontal direction by insulator chain, parallel link plate and link plate on connect insulator chain's horizontal connection rod, the connecting rod both ends be equipped with with insulator chain swing joint's coupling assembling. The conductor spacer, through to installing the conductor spacer among the transmission line on the suspension insulator additional, solved between the suspension insulator wobbling problem each other, improve the security and the reliability of circuit.
