The utility wires are tightened to the point that they allow for thermal expansion / contraction, and still say within the ability of the wire to carry a tensile load. Were the wires made "perfectly straight", there is no real material that could take the load, any real material would start sagging again as the temperature increased, and would break as the temperature dropped. Additionally, the supporting "poles" depend on the the two departing wires to cancel out in tension. Should one of them break, the supporting pole would have to be much more massive than it currently is to keep from breaking too.
Electrical wires are not strung tightly to allow for some flexibility and movement due to factors like temperature changes and wind. This helps prevent the wires from snapping or breaking under stress, ensuring reliable power distribution.
Electric wires are usually made up of aluminum wires ,due to their metallic properties these wires get contracted in winters so to prevent their breakage they are stung loosely.
Wires will always sag however much tension there is. An inch of wire in the middle of a perfectly horizontal long wire has no component of force supporting its weight, so it will drop and the wire has to sag. Power lines are tensioned as much as possible for safety, leaving some sag.

What will happen to the telephone lines if they are fitted tightly from pole to pole?
When a pole shifts with the earth it will pull the wires apart and cause a break somewhere in the line. The poles are meant to suspend the wires in air, not to stretch them... Accurate answer is the lines will break. While breaking is not normally due to poles shifting, that could happen. The reason the wires are slung loosely is because of the expansion and contraction properties of the metal wires. If you look at the lines in the winter, they do not sag much (are tighter) and in the summer the sag is pronounced (looser). If they were strung tightly, they would eventually break during the cold weather.
Which metal is commonly used in electrical wires?
Copper is the most common metal used in electrical wires due to its high conductivity and ability to easily carry electrical currents.
What is copper used for as an electrical conductor?
Wires.
Why wires are made of cooper?
Electrical wires are made from copper, as copper is a good conductor of electricity.
How do you remove the 3 wires from the back of a switch plate when they are tightly packed and will not budge?
Use a small screwdriver to carefully pry the wires away from the switch plate. If they are still stuck, you may need to cut the wires and re-strip them for a new connection. Always turn off the power before attempting to work on electrical components to avoid injury.
Why are overhead electricity cables never tightly over a pylon?
Overhead electricity cables are not tightly strung over a pylon to account for factors like temperature changes, wind-induced movements, and maintenance needs. Having some slack in the cables helps to reduce stress on the wires and prevent damage or breakage.
What would you use pliers for?
You use pliers as a handy single handed way of holding small objects tightly, or for twisting 2 wires as in an electrical connection.
What does taut mean?
It means the quality of being tightly strung, either literally or figuratively.
