![]() ![]() The results show that the original stress is significantly smaller.In this paper, the stress formula is almost close to the reality. And then it gives the line shape formula, internal force formula, formula of stress in the strands. The author establishes a model of wire calculation under real condition, and gives a feasible simplified model. However, the catenary has been used in previous research and the force of the overhead lines is obtained on this basis. Because the stress is the strength of a certain point, the bending rigidity of the overhead lines can not be ignored. And the flat wire is basically in the elastic range. It fully considers that the conductor is subjected to axial force, shear, bending moment simultaneousiy. This paper discusses the issue of shape and stress of overhead transmission lines.
