Besides engineering design request and the standar

3、d design process, this paper mainly include following task in term of the voltage rank, the type of 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 cor

4、ner tower, ulteriorly confirm towers height, the type and amount of 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 conductor and ground wire. II The achievements in this paper includes the instruction the book
