heya..
here is Ur answer..
Because the cores of overhead wiresare made from copper. Metals expand with heat and contract with cold. The higher temperatures in summer make the copper expand - so the lines get slightly longer. In winter, the reversehappens - the lines contract and tighten up
hope this helps u......

⚫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.
