You may also notice, higher voltage lines, as an industry standard, always cross above lower voltage lines. Some EHV transmission line crossing towers can be several hundred feet tall because of this.

Effect of Increasing Transmission Tower Height on Line Capacitance and Line Inductance
Increasing the height of a transmission tower has a direct impact on the line capacitance and line inductance of the transmission line.
Line Capacitance
- When the height of the transmission tower is increased, the distance between the conductors also increases.
- This increase in distance results in a decrease in line capacitance.
- The line capacitance is inversely proportional to the distance between the conductors, so as the distance increases, the capacitance decreases.
- Therefore, increasing the height of the transmission tower will lead to a decrease in line capacitance.
Line Inductance
- The line inductance is primarily determined by the physical properties of the transmission line such as the number of turns, spacing between conductors, and the diameter of the conductors.
- Increasing the height of the transmission tower does not alter these physical properties, so the line inductance remains unchanged.
- Therefore, the line inductance will not be affected by an increase in the height of the transmission tower.
In conclusion, when the height of a transmission tower is increased, the line capacitance will decrease due to the increased distance between conductors, while the line inductance will remain unchanged as it is determined by the physical properties of the transmission line.
