Abstract:

Wires overhead power lines (PTL) are complex structures formed by layers of wire (povivami) wound on each other at different angles relative to the core (wire in the center of the wire). The wires forming the coils of one, are made of the same material. In most cases, coils of wire made of various materials (steel-aluminum wire). In this paper Each layer is represented from the perspective of the energy approach as equivalent to the elastic properties of anisotropic cylindrical shell, and the wire is considered as a system of nested cylindrical shells. Under this approach, the formulas for determining the compliance matrix and stiffness wires
