T he maxi mum stress occurs at the lower t emperature,when the line i s subjected t o contractio n, and a possible ice coating. Moreover, it should be considered that can simultaneously be and wind pressure on the line. To address the se conditio ns, a require me nt, is knowledge of the arr ow of the conductor . Besides, t he arr ow determines the heigh t and strength of the su pporting to wers, as well as t he span length ( distance between two towers). 1.
