Abstract

As the increase of the voltage level and the sag of jumper,the size of the top hamper of tower and the width of the line corridor have to be increased,so the wind deviation swing will increase.In order to ensure the clearance between the jumper and tower,cage-shape hard jumper is employed in the tension support of 800 kV YUN-GUANG UHVDC project.In this article,the installation technique of this kind of jumper was discussed.
