Key Advantages
Non-Conductive Roller Structure for Cable Protection: Features a non-conductive roller design that guides OPGW and static wires while minimizing direct abrasion on cable surfaces.
Multiple Sheave Configurations: Available in single sheave, three-sheave, and five-sheave models to accommodate various stringing layouts and installation requirements.
Large Sheave Diameter Options: Offers sheave diameters including Φ508mm, Φ660mm, Φ822mm, and Φ916mm to support cable guiding work requiring precise bend radius control.
Suitable for OPGW and Static Wire Installation: Specifically designed for safe installation of OPGW, static wires, and overhead grounding wires in transmission line construction and grid maintenance projects.
Reduces Cable Abrasion: The roller structure minimizes contact damage and surface wear on OPGW and grounding wires during stringing operations.
Supports Bend Radius Control: Large sheave diameter options maintain smoother cable paths, protecting OPGW optical fibers from excessive bending stress during installation.
