However large horizontal V assemblies lead to considerable conductor movements due to wind, unbalanced ice accretion and short circuit stresses which can cause: - reduction of phase lo phase clearances; - rotating crossarms instability. An analysis of these movements is therefore essential for the tower head design and for the choice of optimum span length. So, in the optimum compact line design it is necessary to define criteria which may be used lo verify that the above mentioned phenomena are not dangerous in respect of phase-to-phase insulation and possible crossarms failure. In this paper some possible criteria arc suggested and discussed. Mathematical models which can be used for the analysis of the above mentioned phenomena are proposed. An analysis carried out on 420 Kv lines is presented as an example.
