The report presents a mathematical method and the afferent computer programme which solves a determining loading case for the longitudinal stress of the suspension tower: unsymetrically ice charge. that could be a damage generating phenomenon in transmission line exploiting. The programme gives:
- the difference of tension on the adjacent towers of the loaded span. Purpose:the check of towers at the longitudinal unbalance and the slip
of conductor from the suspension clamps;
- the increase of sag at the unsymmetrical load. Purpose: the check of ground clearance for crossings;
- the displacements of the suspension insulator strings at the sudden discharge of load. Purpose:the check of the designed electrical
clearances;
- the jump of the conductor at the sudden ice unloading.Purpose: the check at the phase-phase and phase-ground discharge; - the released energy at the ice dicharge. Purpose:the check of the location points of the vibration dampers and of the vibration spacers.
