Abstract: Aiming at the lower lightning withstanding level of 110kV overhead line in Fuzhou area, for the purpose of decrease the rate of shielding failure, a typical design scheme of steel tower with zero shielding angles was put forward. The selection of lead arrangement mode, the analysis of lightning protection performance and optimization of tower structure in the typical design were discussed emphatically, and the synthetically economic and technical target of the designed steel tower were compared and analyzed.

Key words: design of 110kV level steel tower, zero shielding angle, lead arrangement mode, lightning protection performance, optimization of tower model
