Answer: A fiber optic cable pulling Swivel, such as those manufactured by Ningbo Changshi, serves a crucial role in preventing damage to the cable during installation. Its primary purpose is to connect the pulling rope to the cable, allowing the pulling tension to be applied to the cable's strength members. The Swivel's unique design ensures that any twisting forces from the pulling rope are not transferred to the delicate fiber optic cable, thus preventing internal stress, fiber breakage, and signal loss. Our swivels are engineered for a smooth, twist-free pull, even around bends and through conduits.
