When will a telephone wire be longer summer or winter?
When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.
Why is it important to not overstretch telephone wires when putting them in summer?
When they get colder, they will get shorter - and the tension will increase. That might make them break.
Why telephone wires need to be slack in the summer?
Telephone and electric wires stretch (expand) when the weather is hotter. Conversely, in the winter they shrink. Without some slack, they could become too tight and break, or pull loose from their anchors.
How telephone wires connected?
I'll take that as "How are telephone wires connected?" but it's still unclear what you want to know. Telephone wires are connected just as any other wires are connected. By screw connections, by soldering, by crimping.
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.
Why do telephone wires hang loosely in summer time and straight and taut when it is cold?
Telephone and electrical wires "sag" in the summer, in hot weather. This is because the wires, like most materials, expand when they are heated. The additional length means that the wires lose tension and sag or droop. In the winter, the wires become shorter, and they may break if too tightly strung.
Why is copper used for telephone wires?
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
