Abstract:

The extra strong aluminum conductor steel supported (ACSS) was applied in Lihui-Zhanwang 220 kV double circuit transmission project. Based on this project, this paper studied the construction technology of fabricated stringing in continuous strained section. The theory and method of line length calculation and fixed length manufacturing was investigated for fabricated stringing projects. Finally, this paper introduced new strain clamp technology for fabricated stringing projects, as well as suggested the solution for line length error.
