Abstract:

Zhoushan-mainland transmission line locates in the international waterway, therefore some technical problems such as intensive tension, strong wind and non-closure of navigation need to be solved during the construction. In the paper, the installation scheme of overhead conductor and ground wire are introduced including the determination of key technical parameters, selection of rope pulling methods, and extension of primary and transition guide rope. Furthermore, the measures and strategies for solving the vital technical problems are provided so that the installation scheme is optimized and the successful implements of large-crossing stringing ensured.
