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 wires hang loose on poles in summer?

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.
