Estimation of Overhead Transmission Lines ACSR Combined Elastic Coefficient

Abstract:

According to the characteristics of the aluminum conductors, coated-steel reinforced (ACSR), combined the feature that isotropic and continuity of the folded yarns, establish the calculated equation of the Poisson ratio of the discrete and anisotropic wires. After given the calculated equation of stiffness of large cross-section wires, we obtained the calculated equation of elastic modulus, shear modulus and Poisson ratio. These wires stiffness not only reflect the characteristics of the composite material, but also provide guidance and reference for the mechanical calculation of the wires and installation of overhead conductor and ground wires and the following equation also has certain value in mechanics calculation and lines of construction.
