Electrical wires are not strung tightly to allow for expansion and contraction due to temperature changes. When wires heat up, they expand, and when they cool down, they contract. If the wires were strung tightly, this thermal expansion and contraction could cause stress on the wires, leading to potential damage or failure. Allowing for some slack in the wires helps to accommodate these changes and maintain the integrity of the electrical system.
Oh, dude, you're asking about electrical wires now? Well, they're not strung tightly because they need some room to breathe, you know? Like, they expand and contract with temperature changes, so if they were pulled super tight, they'd be like, "Help, I can't move!" So, it's all about giving those wires a little freedom to do their thing without getting all tangled up.
Well, friend, electrical wires are not strung tightly to allow for expansion and contraction due to temperature changes. Just like a happy little tree sways in the breeze, the wires need a bit of room to move without getting stressed. This helps prevent damage and ensures a smooth flow of electricity, creating a peaceful and harmonious connection.
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.
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.
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.
Copper is the most common metal used in electrical wires due to its high conductivity and ability to easily carry electrical currents.
Wires.
Electrical wires are made from copper, as copper is a good conductor of electricity.
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.
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.
You use pliers as a handy single handed way of holding small objects tightly, or for twisting 2 wires as in an electrical connection.
It means the quality of being tightly strung, either literally or figuratively.
