The position-limited anti-dancing technique of conductor for overhead transmission lines was researched based on the galloping characteristics of overhead transmission lines combined with the technical parameters of conductor, splitting numbers and arrangement form. By analyzing the dancing characteristics, we put forward an anti-dancing mechanism and anti-dancing technology of conductor for overhead transmission lines. Using the finite element analysis software, we carried out the mechanical simulation analysis of the proposed conductor’s position-limited anti-dancing scheme for overhead transmission lines. Trial-manufacture sample of a new design position-limited preventive device was tested, such as mechanical properties test, electrical performance test, assessment test of dancing control effect, etc. The results of pilot application of position-limited preventive device verify that the newly proposed conductor’s position-limited anti-galloping technology for overhead transmission lines can effectively enhance the anti-dancing capability of overhead transmission lines, and guarantee the safe operation of lines.
