Abrégé
(EN)
The invention relates to a power transmission line and a gas insulation line. The power transmission line comprises three sub-pipes connected in sequence in an insulating manner; each sub-pipe comprises a metal shell, and both ends of the power transmission line are earthed. In addition, the gas insulation line comprises multiple connected pipe units; each pipe unit comprises an A-phase pipe, a B-phase pipe and a C-phase pipe; three sets of crosswise interconnected electrical loops comprising A-phase sub-pipes, B-phase sub-pipes and C-phase sub-pipes are formed between the three phases of pipes. The technical scheme provided by the invention has the following technical effects: the three metal shells with different phases are interconnected and form an electrical loop with the ground, so that the induced electromotive force generated by the whole electrical loop can be basically mutually counteracted, the induced current generated in the electrical loop is reduced to a great extent, the heating phenomenon of the metal shell is reduced to a great extent, the power transformation loss is reduced, the safe operation of the equipment is improved, and the economy of the power transmission system is improved.
