Its depends on location and type of towers. Supposed the transmission line is erected at hill area and second line is erected in desert area and third one in forest area. Then the allowable value of weight span and wind span ratio in transmission line will different. Also this ratio will depends on types of tower . Like the value is different in 132KV, 220KV , 400KV and 765KV.
Transmission line can be on H frame up to 66 kv, it can be on structral hollow MS/ wooden high Mast similar one used for illuniating open area , or letice strcutral tower , this depends on level of volatge and type of conductor, land profile and tower spoting.

Lattice steel tower consist of:- 1- Main members. 2- Bracing members. 3- Redundant members. Steel Bracing is the connection between main members of lattice steel tower.
It is necessary because lightning can destroy whole phase conductors. Lightning has energy of 1MHp. So much high energy if falls on transmission line will not even destroy it but all of the distribution systems too. The reason that lightning falls on tower is that it always chosses the shortest path.
The current angle of the tower is about 3.97 degrees.
Kiel Transmission Tower was created in 1975.

If a guy wire from the top of a tower forms an angle of 75 degrees with the ground, and is 55 feet from the tower, then the tower is 205 feet tall.The tower is the side of a right triangle that is opposite the angle in question. The adjacent side is the ground distance, or 55 feet. Tangent theta is opposite over adjacent, so tangent 75 is opposite over 55, or opposite is 55 tangent 75.The guy wire is the hypotenuse in this case, but its length does not matter to the solultion of the question.
PLS CADD for towen design & tower spotting
ask the tower to repeat the transmission by saying say again
11 degrees to the southeast.

A girl 1.2 m in height is 25 m away from a tower 18 m high. What value is the angle of elevation of the top of the tower from her eyes?
. The angle of depression of the top and bottom of a tower as seen from the top of a 100m high cliff are 300 and 600 respectively. Find the height of the tower.?
Depends which angle you look from.
Given the following information provided, it is 19.5 meters away from the tower.
