摘要：
The process of multi-span tension stringing in transmission line is analysed based on elastic catenary equation. From the tower condition of transmission line, the conservation equations of span spacing and elevation difference are built for conductor, and the tension balance equations of conductor between different spans are got considering the rolling friction of the pulley. Added the external tension condition, the overall nonlinear equations of multi-span tension stringing are set up which can be solved by Newton iteration method. The iterative process is listed for the calculation of the conductor tension and sags in engineering problems. Compared the results with the numerical example, this method are proved the reliability. The calculation amount, efficiency and accuracy of this method can meet the needs of the practical engineering.
