What happens to the tension in a conductor hanged between two poles, when temperature varies?

The tension in a conductor suspended between two poles is affected by temperature changes due to the thermal expansion of the material. When the temperature increases, the conductor expands, which generally leads to a decrease in tension if the ends remain fixed. Conversely, when the temperature decreases, the conductor contracts, which typically results in an increase in tension. This is because the length of the conductor changes with temperature, impacting the tension due to its weight and the forces acting on it.
