High transmission lines are placed vertical or horizontal and why?

Horizontal arrangement Uniform electric field distribution: In the horizontal arrangement, the three-phase conductors are on the same horizontal plane. This arrangement helps to make the electric field distribution around the conductors more uniform. A uniform electric field distribution can reduce
