The research of conductor selection is one of the key technologies in UHV AC transmission project. Especially in high altitude area,because the relative density of air is greatly reduced,the research of conductor selection is vital to the reliable operation of transmission line,the environmental protection and project investment. According to the limit value of electromagnetic environment in 1 000 kV UHV AC transmission line,the altitude limit of the electric field intensity ratio and audible noise is studied when multiple split composite conductors are applied to 1 000 kV UHV AC transmission line. At the same time,combined with the annual cost of conductors,the conductor selection related to the corresponding elevation is recommended. After the research,at the altitude of 1 500 ~ 2 000 m,it is recommended to use 8 × JL/G2A - 720 /50 conductor,and at the altitude of 2 000 ~ 3 000 m,it is recommended to use 10 × JL/G1A - 630 /45 conductor.
