An overhead power line is an electric power transmission line suspended by towers or utility poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of transmission for large quantities of electric energy. Towers for support of the lines are made of wood (as-grown or laminated), steel (either lattice structures or tubular poles), concrete, aluminum, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum (either plain or reinforced with steel, or sometimes composite materials), though some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises. A major goal of overhead power line design is to maintain adequate clearance between energized conductors and the ground so as to prevent dangerous contact with the line. Today overhead lines are routinely operated at voltages exceeding 765,000 volts between conductors, with even higher voltages possible in some cases.

What NOT to Do on Power Lines
Can you imagine someone being true
Turn 'round and put himself in front of you
Sometimes it's fun but then you never know
How far a thing like this might go
All my life I've waited for a chance to get right out of here
And when I had it in my hands I could not let it go
We've got the power, we are divine
We have the guts to follow the sign
Extracting tensions from sources unknown
We are the ones to cover the throne
Try if you can to come where we have gone
You may achieve what can't be simply done
Look back and there you are where we have been
And still there's so much in between
All those years I've traveled 'round this world, now I am standing here
To make you sing these tunes and know they'll never let you go
We've got the power, we are divine
We have the guts to follow the sign
Extracting tensions from sources unknown
We are the ones to cover the throne
We've got the power, we are divine
We have the guts to follow the sign
Extracting tensions from sources unknown
We are the ones to cover the throne
