Sag is generally limited to <2% of span length and maximum tension <30% of cable minimum breaking strength. Planning for aerial cable installation includes taking into account proper clearances, cable types and properties, and the mechanical stress loading on the cable. Understanding the expected. Sag, in structural and civil engineering contexts, refers to the downward displacement or deformation of a structural element under its own weight and applied loads. A sag calculator is a computational tool, either software-based or formula-driven, used to predict this vertical displacement. Failure to do so can result in life-threat t truck or on a ladder so that it cannot fall. Materials and equipment should not unnece lled for in your company's safety proced s and, if necessary, lineman's rubber gloves. This guide. The Fiber Optic Association, Inc.
