As the transposition design of 1 000 kV UHVAC double-circuit transmission line was complicated,the advantages and disadvantages of three-column transposition tower were analyzed.According to the disadvantages of three-column transposition tower,which were more occupied land,complicated jumpers and high construction requirements,a new type of tower named double-column transposition tower was researched.The jumpers' arrangement,electromagnetic environment,lightning protection level,jumper fitting strings'design of double-column transposition tower were introduced. Compared with the three-column transposition tower in corridor area,tower weight and other comprehensive economic indicators,it shows that double-column transposition tower has more superiority and practicability.
