Electrical transmission towers are what holds power lines up. These towers are made of steel and have an openwork lattice design.
50,000AnswerIt depends upon the function of the power line, and where it is situated. For example, in the UK, transmission lines operate up to 400 kV; distribution lines run up to 132 kV; low-voltage lines run up to 400 V.
Transmission lines
High power transmission lines carry several hundred amperes up to 2000 amps at voltages up to 500 kV or higher

there are no underground power lines but a zone holds it (power) cause the buildings need power so they hold it. and form like a circuit or you call it a underground power line.
Power lines are made of aluminum, because they are exceptional conductors of both heat and electricity.

there are no power lines in heaven
The sleet clings to power lines and transformers. As the weight of this ice builds up, it breaks the line away from the power pole. It also knocks branches from trees which can also break the power lines.
A step-up transformer is a transformer that increases voltage that is transferred through power lines.
No, but the main concern is that they don't get tangled up in power lines.

Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
