Finite element simulation of wire’s sag considering tension insulator string

A finite element simulation process based on methods of mutual calling between MATLAB and ANSYS software packages are proposed, which has the ability to consider the influence of tension insulator string weight on the sag of a span in a tension section. The convergence criterion of the process can b...

The convergence criterion of the process can be controlled artificially and is defines to converge when the maximum sag of two calculation steps is very small.
