This paper presents the design and the study of a nine-phase transmission line system. Two lines (400 kV over 200 km and 400 kV over 600 km) are implemented using Matlab/Simulink to solve problems of environmental damage caused by several lines located in the same place, the multiplicity of electric faults and the poor power capability transmitted of the three-phase systems. The results obtained show that nine-phase line system could connect up to 9.6 times more load than that of a three-phase line system.
