Equipment for Steel Stranded Fiber Optic Cables

Steel stranded fiber optic cables require specialized production machinery, aerial installation tools, and splicing equipment to ensure safe, efficient deployment and high-quality performance.

Production Equipment

For manufacturing steel-reinforced fiber optic cables, SZ-stranding machines, extrusion lines, and jacketing equipment are essential. SZ-stranding ensures precise twisting of fibers around a steel messenger strand, maintaining low tension and consistent lay length, which is critical for outdoor durability and high fiber counts. Secondary coating lines produce dry or jelly-filled loose tubes, while extrusion lines apply protective jackets using materials like PE, PVC, or UV-resistant compounds. Armoring equipment handles steel tapes or corrugated metal for additional mechanical protection, and integrated monitoring systems assess fiber length and quality in real time to reduce scrap and ensure uniformity .

Aerial Installation Equipment

For field deployment, steel-stranded fiber optic cables require:

• Cable Lashers: Machines like the GMP Apollo, J2, or DCD Lineman Lasher wrap stainless steel lashing wire around the fiber cable and supporting strand, securing it to poles. Features include parallel-pull capability, automatic drum locks, and adjustable strand rollers for overlashing multiple cables .
• Fiber Pullers and Blowers: Fiber pullers provide controlled tension for duct installations, while fiber blowers use compressed air to propel cables through conduits efficiently .
• Reel Trailers: Heavy-duty trailers transport large cable spools to the job site, allowing controlled deployment and reducing manual handling risks .
• Aerial Hardware: Suspension strands, clamps, J-hooks, brackets, and ABstraps support the cable along poles. Galvanized steel strands (e.g., 7/2.2 mm) are commonly used for messenger support .
• Splicing Workstations: Portable fiber splicing tables, such as U-TECK's workstations, allow field splicing at pole height or in confined spaces. Accessories include cable management brackets, stand-offs, splice tray holders, and aerial strand clamps .

Safety and Planning Tools

Proper installation requires PPE (hard hats, gloves, steel-toed boots), ladders, bucket trucks, and fall protection. Pre-survey tools like GPS, measuring wheels, and DCP testers ensure accurate pole placement and route planning. Poles must be inspected for structural integrity, and sag, bend radius, and tension must be calculated to prevent cable damage .

Summary

Efficient deployment of steel-stranded fiber optic cables combines high-precision production machinery with specialized aerial installation tools. Key equipment includes SZ-stranding machines, extrusion and jacketing lines, cable lashers, fiber pullers/blowers, reel trailers, aerial hardware, and portable splicing workstations. Proper planning, safety measures, and route surveys are essential to ensure reliable, long-lasting fiber optic networks .
