Sag and tension errors can compromise clearances, safety, and long-term performance in overhead power lines. This article breaks down the five most common factors that throw sag and tension off—during both construction and maintenance—and explains why accurate field measurements are essential across transmission and distribution systems.

Learn how Vulcan’s 10k & 20k Dynamometers streamline transmission line construction with precise sagging, real-time tension data, and seamless Bluetooth sag chart integration.

Learn how the WaveTimer by Vulcan Line Tools improves power line resilience with accurate sag, tension, and temperature measurements using the return wave method. Ideal for distribution and transmission line maintenance.

Storm hardening the grid is crucial to minimizing the damage of storm surges on the economy and the livelihood of regular people. Vulcan Line Tools’ 5k Dynamometer helps ensure the reliability and resilience of electric infrastructure by precisely measuring conductor tension during construction.
