The simple answer is, "Gravity".
Gravity pulls the wires down just as it pulls everything else down. The wires can only be pulled with a maximum tension, and all the while gravity is pulling down.
CU this is the right answer by killerjo
Copper is the element used in coins and electric wirings due to its excellent electrical conductivity and corrosion resistance.
They are not grounded therefore can not carry an electrical charge.
because of heat cables expand
The conductor strung between two towers is not as tight as a rod, but has some "sag". The conductor is bit loose between two towers. Generally the permissible sag is about 3% (In India)
Sag refers to the downward displacement of a cable or structure due to its own weight, often observed in power lines or suspension bridges. Surge, on the other hand, typically refers to a sudden increase in electrical voltage or current, which can cause damage to electrical components. While sag relates to physical tension and weight distribution, surge pertains to rapid changes in electrical systems.

It is possible that the electrical wirings are grounded. You'll probably need to get an auto-electrician to take a look at it.
i know someones going to be on this sooooooooo....... they sag because the hydro workers know, from the heat the cbles will sag during the summer, so they start the sag so they cant sag anymore
Sag in electrical engineering, particularly in the context of overhead transmission lines, refers to the vertical displacement of the line due to its own weight and the tension in the cables. It is influenced by factors such as the span length between supports, the weight of the conductor, and the tension applied. Proper sag management is essential for ensuring safety, maintaining electrical clearances, and optimizing the performance of the transmission system. Engineers calculate sag to prevent excessive drooping that could lead to contact with vegetation, structures, or other hazards.
by its wirings...... ^_^
