Large-Diameter 660×100mm Fiber Optic Cable Stringing Pulley Block | Heavy-Duty Overhead Line Guide Roller
Product Overview
The 660×100mm Large-Diameter Fiber Optic Cable Stringing Pulley Block is specially designed for guiding OPGW, ADSS, and communication cables during overhead line construction. The large wheel diameter ensures smooth cable feeding, reduced friction, and excellent protection for sensitive fiber optic cables. Built with high-strength aluminum alloy or nylon wheels and a robust steel frame, this pulley block guarantees stable performance in power line and communication line installation projects.
Product Definition
A stringing pulley block is a guiding roller used to support and route cables during installation. The 660mm large-diameter design minimizes bending stress and prevents damage to delicate fiber optic cables during long-distance aerial deployment.
