Dynamical analysis of various transmission line cables

The main objective of this work is the analysis of the dynamic behavior of new transmission line cables: Tern (CAA), CA 1120 and CA 6201 (alloy); with mechanical tension variable (7 to 36% of the ultimate tensile strength (UTS)) with and without the inclusion of Stockbridge dampers. In order to achieve these objectives a procedure is used based on experimental data obtained by dynamic tests and numerical data obtained through computer simulation of mathematical models (linear and nonlinear) obtained by the finite element method. For low cable load, the nonlinear behavior is accentuated and the results obtained by nonlinear modeling exhibit good accord with the experimental modal data. With an increased cable load, numeric data obtained through the linear and non-linear models are close.
