How do you prevent telephone wires breaking in cold weather?
the wires are made slack so they do not break
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.
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.
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.
Do you capitalize winter break?
Winter break can be capitalized, or lower case. If, on a calendar, you are writing winter break, then you would put "Winter Break". On anything else, it could be "winter break", "Winter break", or "Winter Break".
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.
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.
what would happen if telephone wires were made tight in summer and then it went cold?
so it can survive
When is the winter break in football?
There is no winter break in football.
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).
Why do telephone wires become loose and sag in winter?
They shouldn't, usually it is the other way around. As with all wire, the temperature effects wire lengths. When wires become warm as in a hot summer day the wires expand and droop and likewise when they become cold as in winter they contract and tighten up. The wires have to be installed to take this condition into consideration. There is a specific engineered sag allowed for each type of conductor from pole fix point to pole fix point.
How many hours is winter break?
336 hours are in a winter break.
