Economic activity in the line corridor
In case of an overhead line, the conductors need to have a minimum clearance to the ground and as such allow for economic activities below the line. Especially agriculture is easily possible. In the area underneath as well as to the side of the line, there are height restrictions that cannot be exceeded, for instance by trees, to avoid short-circuits.
In case of an underground cable, the corridor can also be used for agricultural purposes or planted with vegetation after the construction phase. Only in the area above the trench and about three metres on both sides, no deep-rooted and hard-rooted trees and shrubs are allowed to grow, in order to prevent damage to the line. No buildings are allowed directly above the trench either.
