Besides engineering design request and the standard design process, this paper mainly include following task in term of the voltage rank, the type of HYPERLINK javascript:showjdsw(showjd_0,j_0) conductor and ground wire, the condition of weather and landform. Firstly, we calculate the stress of the wires, and draw out its chart. Secondly, we choose the type of straight line tower and the corner tower, ulteriorly confirm towers height, the type and amount of HYPERLINK javascript:showjdsw(showjd_0,j_0) insulators and fittings. Thirdly, we repetitiously arrange the tower position on the plane cross section by the template of arc sag. Fourthly, we check the load of towers and the stability of tower foundation. Finally, we design the shockproof of HYPERLINK javascript:showjdsw(showjd_0,j_0) conductor and ground wire. The achievements in this paper includes the instruction the book and the account book, in which the formulas and its application are detailedly recorded, in which the design content and points for attention are concretely listed also. Deservedly, the drawings in the appendix belong to the part of the achievements in this paper also. Key Words 220kV overhead transmission line, the calculation of stress and the sag height , arrange the tower posi
