A complete set of tension backup device for carbon fiber wire, comprising a backup tension device (1), a performed armor rod (2), a parallel hanging plate (3), an adapter base (4), a wire drawing device (5), a support damper clamp (6), U-shaped pulling ring (7), a triangular hanging plate (8) and a tensioning device (9), wherein a surface of the carbon fiber wire at installation position of the backup tension device (1) is provided with the performed armor rod (2);
- a hanging plate (13) of the backup tension device (1) is connected to the adapter base (4) through the parallel hanging plate (3) and the tensioning device (9);
- one end of the wire drawing device (5) is connected to the adapter base (4) through the U-shaped pulling ring (7), an other end is connected to the tensioning device (9) arranged on the triangular hanging plate (8);
- the triangular hanging plate (8) is arranged on a fixed pole tower;
- the backup tension device (1) is a wedge-shaped backup strain clamp;
- the performed armor rod (2) is a wear-resistant pre-twisted wire;
- the support damper clamp (6) is arranged on carbon fiber split wire between an original strain clamp and the backup tension device (1) and arranged at intervals of 3-4 meters;
- the tensioning device (9) is a turn buckle with a closed-loop buckle at both ends.
