| Abstract: | This paper expounds types of poles and towers for DC transmission lines,arrangement pattern of lines,combination mode of insulator string and places where it is employed.It comprehensively demonstrates optimal design of high-load DC transmission lines in terms of selecting tower type and arrangement of tower head,calculation of wind vibration coefficient of tower body and load combination.It is pointed out that wind vibration coefficient can be reasonably and reliably calculated in accordance with Q/DG 1-A012-2008 Guiding Rule for Design of ±800 kV Overhead DC Transmission Lines. |
