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.

∙ 12y agoThis question has been asked in numerous forms. In summer, when the weather is warmer, the cables stretch slightly. This causes them to sag between the poles. In winter, they contract - so look tighter.

∙ 9y agoIf you are referring to pairs that are to be punched down on a terminal strip, it is so that they can be easily removed and punched down on a different position on the terminal strip if a fault occurs on the line that it is originally connected to. In short for ease and flexibility of maintaining the circuits.

Why are telephone wires left slack in the summer?
Bofore the question can be answered, it needs to be properly rephrased.The question contains a grammar error that is all too frequent these days... non-agreement with the subject in number (singular or plural). We need to be more careful of such simple grammar slip-ups. Poor grammar betrays a lack of education and an imprecision of thought.Correction: Why are telephone wires left slack?This error is creeping into speech today...from even the news anchors... through the contraction of "is" following the word "there", e.g. "there's too many jobs being lost...".Correction: There are too many jobs being lost...
What did Alexander Graham Bell need to know in order to create the telephone?

Why does the telephone need wires?
Actually it doesn't. You could talk on the telephone all day and night without wires. You only need wires if you want anyone else to hear you when you speak, or if you want to hear what anyone else has to say. The telephone was invented a long time before radio. By the time radio was first invented, virtually every home in the US was wired to central telephone offices, and it was another long time after that before radio equipment could be made small enough and cheap enough to make radio-based telephoning practical. That only happened within the past 20 years or so ... less than 1/6th the length of time that the telephone has been around.
Why do birds sit together on telephone lines?
For a start, most telephone wires are insulated and carry little or no electricity so, apart from falling off and hurting themselves, they won't get hurt on telephone wires. Really, you should have asked about why birds don't get hurt on overhead electrical wires. The answer is fairly simple really - to get electrocuted from those wires you need to complete the circuit, in this case touch the ground, for the electricity to surge through the body. Birds only sit on the wire and do not touch the ground, so they can't be electrocuted.

What is the difference between manual and automatic slack adjusters?
The difference between manual and automatic slack adjusters is the way in which the brakes are adjusted. Automatic slack adjusters have sensors that do not let the brakes get too loose or too tight. Manual slack adjusters have to be adjusted by hand and can be set too tight in some cases.
