What is a "stringing chart" and why is it important for overhead line construction?
2025-08-13Our Answer: A stringing chart is a critical tool for the precise installation of overhead line conductors. It is a technical document that provides the correct sag and tension values for a conductor at different temperatures and span lengths. During the construction of a new line or re-conductoring, our crews use the stringing chart to ensure the conductor is installed with the optimal tension. This is essential for:
-
Safety: Maintaining proper ground clearance to prevent accidents.
-
Reliability: Preventing excessive sag that could cause the conductor to touch other objects or conductors, leading to a short circuit.
-
Longevity: Avoiding excessive tension that could stress and damage the conductor or the supporting structures.
