| Abstract: | As a new voltage class in China,the ground clearance and crossing clearance of the ±800 kV transmission line have significant impacts on project investment.In order to meet the engineering construction needs,based on domestic and international data and the research results of ± 800 kV Xiangjiaba-Shanghai DC transmission line,the required ground clearance and crossing clearance of conductors are determined according to different field strength standards and air clearance requirements in various regions.In the end,the recommended ground clearance and crossing clearance of conductors are proposed for ±800 kV Xiangjiaba-Shanghai DC transmission line. |
