Telephone wires are strung with a sag between poles to ensure that they can withstand environmental factors such as wind, temperature changes, and ice accumulation. This sag allows for some flexibility, preventing the wires from becoming too taut, which could lead to breakage or damage. Additionally, the sag helps maintain the proper clearance from the ground and surrounding objects, ensuring safety and functionality.

Why are telephone poles called telephone poles?
Telephone poles are just wood poles that hold the telephone cable,the telephone terminal and telephone drops, (wires going to individual houses) in the air and out of the way. Areas that have no poles usually are newer areas, they have the same type wires only they are buried in the ground.
What would happen if telephone wires were pulled tight between the poles during construction?
If telephone wires were pulled too tight between the poles during construction, it could lead to excessive tension on the wires. This could cause them to snap or break, potentially leading to service interruptions and safety hazards. Additionally, the poles themselves might be stressed beyond their structural limits, risking damage or collapse. Proper tensioning is crucial to accommodate temperature changes and prevent such issues.
What are environmental disadvantages of telephone wires?
Other than the pollution that comes from making wires, insulation, metal for transformers, and logs for poles, not much.
Did the telephone have a positive impact on the environment?
the telephone did and did not help the environment. It did help, because less trees were being used to write letters. But it didn't help too, because of the telephone wires and poles. They got in the way of animals. The telephone did however, give more jobs to others, and helped many people contact others.
What are the wires for on telephone poles?
Quite variable according to local practice. May include AC power, telephone, and/or TV cable service.
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.
Where strung across the continent bringing communication to people from far distances?
Telegraph wires were strung across the continent to bring communication to people from far distances before the invention of telephone or internet. These wires allowed messages to be transmitted quickly and efficiently over long distances, revolutionizing communication in the 19th century.
What is the difference between 0.51MM 0.61MM telephone wires?
.10MM
When were telephone poles invented?
Samuel Morse invented the telephone pole after trying to put the wires underground, which did not work. The United States government gave him $30,000 to figure this idea out.
How are cellphones good for the environment?
Before cell phones all telephone messages ran along wires. Wires and poles were set up all over countries, often using electricity poles. These poles and wires are a visual blot on the landscape, but don't damage the environment too much. Cell phones may mean that we can do without the poles and wires, especially if electricity wires are put underground or if everyone has solar panels good enough to be independent.
Where are the telephone poles on Big Nate Island?
On either side of the businesses on Main Street. You can climb any pole because they are all connected by springy wires.
Were there direct wires in telephone between NYC and Palm Beach in 1907?
It is unclear if there were direct wires in telephone between New York City and Palm Beach in 1907. Telephone systems had not yet been standardized, and the technology of the time was limited. It is likely that telephone calls between the two cities would have required operators to connect the call manually.
