The invention discloses a combined damper. The combined damper comprises dampers and wire clamp pressure plates, wherein the damper comprises a stranded steel wire; the two ends of the stranded steel wire are connected with damper heads; the wire clamp pressure plate is provided with a wire clamping hole, and is provided with at least two damper clamping wings at intervals; the damper clamping wings are provided with stranded steel wire clamping holes of the damper; and the stranded steel wire of the damper is clamped in the stranded steel wire clamping holes. A plurality of dampers are arranged, so anti-vibration frequency is much higher than that of the current single damper. Simultaneously, the dampers are arranged on a ground wire along a plurality of directions, so the ground wire can be balanced and the anti-vibration effect of the ground wire is further improved.
