The invention discloses a lightning arrester line live-line equipotential entering safety method, and relates to the technical field of power construction. The method comprises the following steps: step a, wearing a whole set of shielding clothes on the ground; step b, carrying an insulation carrying tool to climb the iron stand upwards to the height wherein the electric wire is located; and stepc, erecting one end of the insulation carrying tool on the iron stand, erecting the other end of the insulation carrying tool on the electric wire, and then walking to the electric wire from the ironstand. By use of the iron stand, a worker climbs to the height of the electric wire, then by use of the insulation carrying tool, the worker works to the wire, a scissor-fork type operation platform is not needed, and the method is suitable for the field environment with uneven ground.
