Combined with the 500kV conventional line with electric replacement insulator technology, according to the tower window compact features and double back line multi-conductor same tower layout under the combination of the specific tower type and insulator string connection characteristics, the study of the special tower type using the traditional replacement of insulator technology may be the existence of potential safety problems. Combined with the personnel, equipment, environment, entry potential method, maintenance equipment for specific analysis, to determine the entry of equipotential method and the special card for the replacement of insulators with electricity as a 500kV compact double-tower transmission line with electricity to replace insulators of the two key technologies. In this paper, the following research conclusions were obtained: the best way to enter the 500kV compact type same tower double circuit line straight tower on the phase conductor is to climb along the ladder method; the best way to enter the 500kV compact type same tower double circuit line tension-resistant tower inside on the phase conductor is the "three-short-four" method; the best way to enter the line on the right side of the upper phase conductor is the method of swinging into the outside of the stall; the best way to enter the line down the phase conductor is the swinging method of entering the outside of the stall; the best way to enter the lower phase conductor is the method of entering along the jumper.
