Abstract

Abstract: 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.

Key words: UHVAC, double-column transposition tower, electromagnetic environment, lightning performance, technology and economy
