Sag of power transmission optical cable
Sag in a transmission line is the vertical gap between the support points, such as transmission towers, and the conductor 's lowest point. Purpose of Sag: Including appropriate sag protects transmission lines from excessive tension and potential damage, especially under adverse. Planning for aerial cable installation includes taking into account proper clearances, cable types and properties, and the mechanical stress loading on the cable. Before any conductor or OPGW (Optical Ground Wire) is strung between two towers, engineers must carefully calculate sag and tension. Account for cable weight, ice loading, wind loading, and horizontal tension to determine mid-span sag, cable length, and maximum tension. Hence, they are one of the.
