Discussing Chinese UHV Transmission Tower’s Reliability by Comparing Design Standards Home and Abroad

Abstract:

Several representative design standards or manuals of overhead transmission lines home and abroad were selected, including Chinese<Technical regulation of design for tower and pole structures of overhead transmission line>DL/T5154-2002,American<Design of latticed steel transmission structures>ASCE10-97, European<Overhead electrical lines exceeding AC 45kV>EN50341-1etc., compared the reliability level of axial compression member of transmission tower in these standards, by calculating the comprehensive reliability coefficient under the strength limited state. Basically make the selected standards’ level of reliability degree clear, the specific data was got, and then gave some advice to UHV towers’ design about the setting of reliability level, which could not only provide a reference to understand the differentia of design standards home and abroad, but also to design the UHV transmission lines.
