The utility model provides a spacer that conductor spacer for preformed armor rod, it is sticked together by the freedom section in bank at both ends and the whole curved U -shaped form of making of mid portion winding heliciform preformed armor rods together constitutes, and the freedom section in bank at both ends sticks together and constitutes the section of gripping of conductor spacer, wholly is spirally wound on by two wires of spaced, and the supporting is done in the mid portion winding together between two wires. Its processing technology is simple and convenient, and the steady quality, and the uniformity is good, it can with preformed armor rods to lead, the static compressive stress of ground wire uniformly the dispersion to the great region, improve lead, the ground wire goes up abominable ambient stress with gold utensil looks the contact region, make lead, the ground wire avoids destructive vibration and fatigue, has superior fatigue resistance ability, its simple installation is swift, and bare -handed installation does not need the mounting tool, has improved the installation rate of gold utensil and the efficiency of hand labor, the great improvement of spacer rigidity is favorable to resisting horizontal direction pressure, keeps by the interval of two wires of spaced.
