A method for safely equipotentially transferring live workers of an AC power transmission line includes the steps that after an equipotential work body is carried to a to-be-overhauled position of theline by a helicopter, the equipotential work body makes contact with an upper-phase conductor to form equipotential for carrying out equipotential work; after the equipotential work body performs theequipotential work on the upper-phase conductor, a live worker spreads an insulated rope ladder from the upper-phase conductor to a lower-layer conductor of the same circuit, and shifts from the upper-phase conductor to a middle-phase conductor of the circuit in which the upper-phase conductor is located or a lower-phase conductor of the circuit in which the upper-phase conductor is located alongthe insulated rope ladder so as to perform equipotential work on the middle-phase conductor or the lower-phase conductor. The insulate rope ladder is spread along the AC transmission line, the equipotential transfer of the liv
