Yes as though during the hot days the wires due to the hot heat that make it expand.

Does wire expand when heated?

yes wires do because when the wires are heated the particles inside the wires change speed and move faster. this causes them to bump into one another and expand!


Why metal wires sag in summers?

They expand with heat.


Why did railroads and the telegraph expand together?

because telegraph wires were poles along the railroad tracks


What happenes to telephone wires when they expand with heat?

When telephone wires expand with heat, they may sag or become looser due to the increased length. This can lead to potential issues such as interference or disruption to communication signals. Telephone companies often install slack loops in the wires to accommodate expansion and prevent damage.


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.


Why do metallic wires sag in summer?

Metallic wires sag in summer due to the increased temperature causing the wire to expand. As the wire expands, it becomes longer, leading to sagging between poles or supports. This sagging is a result of the wire's thermal expansion and contraction properties.


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.


What is the reason during the summer when they set up electrical cable they allow the cables to sag?

Due to the thermal expansion of the wiring materials, the wires expand in both width and length. This affects electrical transmission lines, telephone lines, and telegraph lines because of the large space between supporting poles. Example : Copper (Cu) Thermal Expansion= 17.6 μm/m/oC


Why do wires sag in summers'?

Wires sag in summers due to the increased temperature causing the metal to expand. This expansion causes the wire to elongate, resulting in sagging. This phenomenon is more pronounced in hotter temperatures as the metal becomes softer and more pliable.


Why are wires hung loosely in summer?

beacuse is good


Why do overhead wires hang with a slight sag in summer time and hang tightly in winter?

Overhead wires expand slightly in the summer when the temperature is higher, so they become a little longer and hang lower. Clearance height rules must be met at the maximum expected temperature.


Why do telephone wires in warm weather slack?

All materials expand with temperature increases. This expansion in the metals and plastics of phone lines would cause them to lengthen, and thus go slack.
