The amount of sag is not static; it is influenced by several key factors. Our expertise in overhead transmission line equipment allows us to address each of these variables with precision:

• Conductor Weight: The natural weight of the conductor is the primary force causing sag.

• Span Length: A longer span between two supports will result in a greater sag.

• Conductor Tension: Sag and tension have an inverse relationship; higher tension leads to less sag, and vice-versa. Maintaining the correct tension is crucial.

• Temperature: As the conductor temperature increases (due to high current or ambient conditions), the conductor expands and its length increases, causing a corresponding increase in sag.

• External Forces: Environmental factors such as wind pressure and ice loading can significantly increase the effective weight on the conductor, increasing the sag.
