Proper sag and tension calculation is a fundamental step in ensuring the longevity and safety of an overhead line. The correct sag, or vertical distance from the conductor's suspension point to its lowest point, must be carefully controlled. Too little sag can cause excessive tension, risking conductor breakage, while too much sag can lead to a safety clearance breach. The calculation is complex and is influenced by factors such as temperature, span length, conductor type, and expected load conditions (e.g., wind and ice). We offer a full range of conductor tension stringing equipment designed to apply and maintain precise tension according to these critical engineering calculations.
