The invention discloses a spacer wire chunk capable of maintaining a torque characteristic in ice coating. The spacer wire chunk comprises a body frame, a spacer sleeve and a wire chunk, wherein a body on the body frame is connected with a cover plate to form an annular cavity; the wire chunk is arranged in the annular cavity of the body frame; the outer wall of the wire chunk and the inner wall of the annular cavity are respectively set as circular rings; the spacer sleeve is arranged between the outer wall of the wire chunk and the inner wall of the annular cavity; the body frame, the spacer sleeve and the wire chunk form a rotation pair; the wire chunk is adapted in the annular cavity rotatably; and flanges are arranged on the two outer sides of the annular cavity of the body frame. By using the spacer wire chunk, vibration, wire collision between wires, breeze vibration and subspan oscillation when overhead power transmission lines are ice-coated are inhibited so as to ensure power equipment safety.
