Abstract

Abstract: The ZB1 cup-type steel tubular tower is firstly used for the single-circuit UHV transmission line in heavy icing area. Except for the ground supports, the steel tubulars are applied in the whole tower. The used tubular steel is Q345 and the plug-in boards and forging flanges are used for connection. Through the monographic study on the tower optimization, node structure, tower’s Eiffel effect and bending moment at the member end, the design of ZB1 cup-type steel tubular tower is improved. The full-scale test verifies the reliability in design and manufacture of cup-type steel tubular tower for UHV lines in heavy icing area. The research results of this paper can be widely applied in UHV transmission line projects.

Key words: heavy icing area, UHV, cup-type, steel tubular tower, full-scale test
