This paper presents the permissible conductor temperature and load current calculation principles. On the one hand, the principles are based on mechanical limitations like the physical characteristics of the conductor, conductor sag, ground clearance and clearance to the crossed objects; on the other hand, thermal limitations, which take into account the mechanical limitation and the climate conditions. A special program was used for mechanical calculation of a particular 330 kV overhead line, which is also presented in the paper. The theoretical background of allowable conductor temperature and load current calculation as well as the simulation results is reviewed in the paper.
