The ground clearance of an overhead line is not static; it is heavily influenced by a phenomenon called sag. Sag is the downward curve of the conductor between two support poles, and it changes with temperature, wind, and ice loading.

Properly maintaining the correct clearance begins with the installation process. Our OHTL wire cable conductor tension stringing equipment is engineered to precisely control the conductor tension during installation. By using our hydraulic pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, technicians can accurately set the initial sag, ensuring that even under maximum sag conditions (e.g., high temperatures), the line will not dip below the required minimum clearance. Our tools are essential for this precision, which is a non-negotiable aspect of power line safety and longevity.
