(1) Determine the transmission capacity, wire and ground specifications, safety factor, before the tower selection.
(2) After mastering the different terrain conditions and meteorological conditions in the area, preferred for the terrain conditions of the rod type (representative of the tower type and the linear tower form), planning a reasonable distance (including horizontal, vertical and maximum gear distance), and the calculation of the design of the tower and towers of the value of comparison and checking, to prove no condensate.
(3) It is convenient to consider the operation and maintenance of the line, inspection and maintenance, safety management, maintenance tools and transportation.
(4) Taking full account of the line construction and transportation conditions, it is necessary to build the road, bridge, artificial lift and other transport engineering quantities and difficulties.
(5) After the comprehensive Economic and technical analysis, determine the tower form. The type and size of the selected towers should be simplified as far as possible, and the selection of tower towers should be preferred to reduce the consumption material.
