How high are the electricity pylons?

A 400,000 volt lattice pylon is typically up to 50-metres high, while the T-pylon stands about 36-metres high. The lower height of the T-pylon is possible because of the new way the cables are held in place.

So, how tall is an electrical tower?

A variety of tower designs exist that commonly employ an open lattice work or a monopole. Transmission towers are generally very tall metal structures (a 500 kV tower might be 150 feet tall with crossarms as much as 100 feet wide).

How tall is a utility pole?

The standard utility pole in the United States is about 40 ft (12 m) long and is buried about 6 ft (2 m) in the ground. However, poles can reach heights of 120 ft (37 m) or more to satisfy clearance requirements.

How high are power lines supposed to be?

Power lines with a voltage above 300 volts require a minimum height of 15 feet. Public and commercial areas, especially those that feature over-size truck traffic, need greater clearance for safety's sake and the National Fire Protection Association suggests a height of at least 18 feet.
