Fiber Optic Cable Suspension String Manufacturer

Leading manufacturers of fiber optic cable suspension strings include ZMS Cable, AFL, PLP, and SAPREM, offering preformed clamps, mechanical suspensions, and hardware for ADSS and OPGW cables.Key Manufacturers and ProductsZMS Cable ZMS Cable specializes in high-end aerial optical cables and accessories for ADSS and OPGW systems. Their preformed suspension hardware is designed to fix conductors on insulator strings or hang lightning lines on towers. Features include large gripping force, lightweight design, minimal corona, and low magnetic loss, making them suitable for 220kV and above lines, heavy ice areas, and long-span projects. They also provide dead-end clamps and tension fittings for low-tension applications, replacing traditional XGU and XGF suspension hardware . AFL AFL offers mechanical suspension systems for OPGW cables that support vertical, transverse, and longitudinal loads across a wide range of line angles. Their lightweight design allows easy installation without specialized torque tools, protecting cable strands and optical fiber performance. Breakaway bolts ensure proper torque, and the assemblies are optimized for fast installation and cost efficiency . PLP (FIBERLIGN® Suspension) PLP's FIBERLIGN Suspension uses structural reinforcing rods, outer rods, and resilient inserts to reduce compression, clamping, and bending stresses on OPGW and optical fibers. While rods are single-use, hardware components can be reused if in good condition. This system is designed to enhance fiber protection and simplify installation . SAPREM SAPREM provides suspension sets for fiber optic cables, including shackles, twisted or eye chain links, armour grip suspension clamps, parallel groove clamps, and earthing connectors. Their products are suitable for standard aerial fiber optic installations and come with detailed diagrams for steel fittings and guy grip dead ends .Considerations for SelectionVoltage and Span Requirements: Choose hardware rated for the line voltage and span length. ZMS and AFL products are suitable for high-voltage and long-span lines.Environmental Conditions: For areas with heavy ice or extreme weather, preformed clamps with damping pads (ZMS) or mechanical suspensions (AFL) are recommended.Ease of Installation: Systems with breakaway bolts or reusable hardware components reduce installation time and maintenance costs.Compatibility: Ensure suspension hardware is compatible with ADSS or OPGW cable types and existing tower structures. These manufacturers provide globally recognized solutions for fiber optic cable suspension, ensuring reliability, safety, and performance in aerial installations.
