How to pull cables when there are too many bends in the cable tray
The Fiber Optic Association notes that a common recommendation is a minimum bend radius of 20 times the cable diameter while the cable is under tension during pulling. When bend radius is a concern, installations typically turn to Cleerline's SSF and BendSafe fiber. This usually occurs when cables are. All guides should be in the form of large diameter, smooth-surfaced, free-turning sheaves or rollers to prevent damage to the cable jacket when guiding the cable from the reel to the duct mouth or trench. Guide tubes or chutes must be smooth, burr-free working surfaces with the largest possible. It happens during installation, when excessive pulling force, tight bends, crushing or poor pathway planning place unnecessary stress on the cable. Excessive pulling tension, improper bend radius, and unsupported pathways can deform conductors, introduce signal loss, and. Here in our area,Cables are traditionally pulled through cable tray by manual labor. I want to modernize this using cable rollers etc.
