Abstract

Abstract: The 900-mm2 large-section high strength steel reinforced aluminum-alloy cable is firstly applied in the Yellow River large-span section of Hazheng 800-kV UHVDC transmission project. In this paper, the key points of the conductor manufacturing process are analyzed with the difficulties of quality control being summarized. Then, the analysis on the quality of the traditional manufacturing method is conducted and the improving measurements are put forward according to the related technical requirements, which solves the problem of quality control of 900-mm2 large-section high strength steel reinforced aluminum-alloy cable manufacturing. Through the improvement of manufacturing process, the conductivity is stabilized at 53%IACS and the strength of single wire is increased to 310 MPa. Meanwhile, the hydrogen and impurity contents are largely reduced by more than 60% and 70%, respectively. Therefore, both the energy economy and the supply security of transmission lines are obtained.

Key words: UHVDC, Hazheng transmission project, long-span, high strength aluminum-alloy conductor, extra high strength zinc coated steel conductor, manufacturing process, quality control
