Abrégé

A power distribution facility live-line working method is disclosed. The power distribution facility live-line working method of the present invention comprises the steps of: erecting a new electric pole on a line of electric wires formed between existing electric poles; fixing an temporary arm part to the new electric pole; binding an electric wire to an electric wire support part provided on the temporary arm part; positioning the electric wire to be in a higher position than the expected installation height of a pin-pole assembly by moving the temporary arm part or the electric wire support part upward; installing the pin-pole assembly on the new electric pole; moving the temporary arm part or the electric wire support part downward toward the pin-pole assembly; and transferring the electric wire connected to the electric wire support part to the pin-pole assembly.
