Arrangement method of large-current cable

The invention discloses an arrangement method of a large-current cable, which is used for arranging a three-phase cable on a support structure, and the support structure comprises a ladder-type bridge and an insulating part. The plurality of insulating parts are arranged on the ladder-type bridge frame at intervals in a crossing manner along the extension direction of the ladder-type bridge frame so as to separate the three-phase cables and enable the distances between the cables to be the same; the arrangement method comprises the steps that at least one support structure is arranged and fixed; a plurality of insulating parts are arranged on the ladder-type bridge frame at intervals along the extension direction of the ladder-type bridge frame; the at least one group of three-phase cables is laid along the extension direction of the ladder-type bridge, and each group of three-phase cables is fixed and separated from each other by using insulating parts.
