In order to reduce the induced voltage of the metal sheath of high voltage single core cable and reduce the excavation area, so as to increase the transmission efficiency and reduce the cost of the project, this paper studies the induced voltage of the cable line under the condition of the laying area. By calculating the influence of any adjacent three phase in double loop and multi loop cable, the influence of the multi loop cable is explored, and a double loop model is established according

... the law. Then, the simulation results of electromagnetic transient simulation software ATP-EMTP are compared with the existing double circuit arrangement method, and the accuracy and feasibility of this method is verified. Therefore, it is suggested that the increase of the land use rate and the two aspects of the induction voltage of the cable metal sheath should be considered when the laying of the multi loop cable.
