The invention relates to a live-line work robot and a pair of live-line wire cutters. The electrified wire cutters comprise a mechanical execution part and an electric driving part, wherein the mechanical execution part comprises a movable cutter, the electric driving part is used for providing power for the mechanical execution part, the electric driving part is in transmission connection with the mechanical execution part through a transmission rod, the transmission rod is an insulating rod, the transmission rod is sleeved with an insulating protection sleeve, the insulating protection sleeve can prevent flashover, and the insulating protection sleeve, the electric driving part and the mechanical execution part jointly define the protection space used for protecting the insulating rod. The electrified wire cutters are advantaged in that the insulating protection sleeve can protect the transmission rod, and flashover of the transmission rod is avoided; the protection sleeve is matchedwith the transmission rod, so the transmission requirement can be not only met, but also the anti-flashover requirement can be met, a discharge protection problem of a transmission structure betweenthe mechanical execution part and the electric driving part is solved, and safe and stable operation and the service life of the electric driving part are guaranteed.
