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.

Every material expands in heat and contracts in cold. The amount of change depends on the material in question. It is important in construction to take this into account. If the cables where hung too tight in the hot summer, when it got cold in winter they would be unable contract enough and would snap. If they where hung loose in the winter, then in summer the cables would sag far too much. An engineer must take this into account when selecting the material used, and planning how much slack to leave to ensure that they will be reliable in hot and cold conditions.
