um... isnt it kinda obvious? they are the cords that hang all over the place that carry electricity.
Insulators.
Increase the voltage in the lines.

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.
Yes and no. First, a history on poles. The reason we call them telephone poles is they were first used and paralleled train tracks and were called telegraph poles. This was pre 1900. Since then, electricity or power lines were strung up on these same poles and power poles, which are owned by the power company. If a pole has both power and telephone on them, they are called joint-use poles and utility companies that own the poles can charge other utilities to use them for a yearly fee per pole. Nowadays, most poles are joint use and carry power, telephone and cable television on them and unless your power is fed by underground or buried power lines, your computer gets the power it needs from these type poles. The exception to this is a battery powered laptop, but these still get recharged by the same source.
Overhead lines refer to electrical power lines that are mounted on poles or towers above ground level. These lines are used to transmit electricity from power plants to homes, businesses, and other buildings. Overhead lines are a common method of distributing electricity in many regions.
The span between two electric poles typically ranges from 100 to 300 feet, depending on the terrain and the voltage of the power lines they support. The span is designed to ensure the stability and safety of the power lines while minimizing the number of poles required.
Yes, lines of longitude converge at the poles, so their distance apart decreases as they approach the poles. At the poles, lines of longitude are essentially touching, whereas at the equator they are farthest apart.
Power lines and phone lines though using the same utility poles are two different sets of wires. Telephone wires carry their own power, separate from the power lines and are insulted while power lines are not. If the telephone wires are unbroken but laying on the ground the wires will not short to ground while an unbroken uninsulated power line will short to ground disrupting service.
There is a rental fee for other lines. This is similar for power companies also. Not all lines are owned by local companies.
Yes, lines of longitude converge towards the poles, so they are spaced closer together as they near the poles. This convergence causes the lines of longitude to become shorter as they approach the poles.
Power lines can be buried underground through a process called trenching, where a trench is excavated and the power lines are laid within it. This method helps reduce visual clutter and protects the power lines from weather-related damage. Special equipment is used to dig the trench and install the power lines before the soil is backfilled to cover them.
Lines of longitude meet at the poles, both North and South. At the North Pole, all lines of longitude converge and meet at a single point. The same holds true for the South Pole, where lines of longitude also converge and meet at a single point.
