You're on a roll — The reason electricity transmission cables are left sagging between the pylons is to allow for thermal expansion and contraction. Cables expand in hot weather and contract in cold weather. Sagging prevents the cables from becoming too taut and snapping during cold contraction, or from stretching excessively and breaking during hot expansion. Next question, Peter! 📸
