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.

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.
What are the examples of electrical energy?
electricity moving on wires
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 is the best way to secure wires and cables together, using a product commonly known as electrical tape?
The best way to secure wires and cables together using electrical tape is to wrap the tape tightly around the wires, ensuring a snug and secure fit. Make sure to overlap the tape to create a strong bond and prevent any exposed wires.
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.
Can you splice wires in an electrical panel?
yes wires is electrical panel
What does taut mean?
It means the quality of being tightly strung, either literally or figuratively.
