Prestranded Suspension Clamp For OPGW Optical Cable | Preformed Helical Armor Grip Suspension

Prestranded Suspension Clamp For OPGW Optical Cable (also known as Preformed Suspension Clamp for OPGW, Helical Armor Grip Suspension, or Pre-Twisted Suspension Clamp) is a high-performance prestranded helical fitting designed for suspending Optical Fiber Composite Overhead Ground Wire (OPGW) cables on transmission towers, particularly at tensile or angle towers. This specialized clamp provides reliable protection and auxiliary damping while eliminating harmful stress concentrations, ensuring the cable maintains its full mechanical and optical performance under dynamic loads.

Key Features and Advantages

• Stress-Free Gripping: The pre-twisted helical design wraps directly around the OPGW cable, distributing loads evenly and preventing point-loading or micro-bending that could damage optical fibers.
• High Grip Strength: Grip force is not less than 95% of the rated tensile strength of the cable, delivering exceptional holding power for long-span and high-tension applications.
• Superior Vibration Damping: Effectively suppresses aeolian vibration and dynamic stresses caused by wind, enhancing cable fatigue resistance and service life.
• Easy & Rapid Installation: Preformed components allow quick hand application without special tools, reducing field labor time and installation costs.
• Robust & Corrosion-Resistant: Manufactured from high-quality aluminum alloy pre-twisted wires and galvanized steel hardware for outstanding durability in harsh outdoor environments.
• Quality Certified: Produced under ISO9001:2008 and ROHS standards for consistent quality and environmental compliance.

Spécifications techniques

Each model is precisely matched to OPGW cable diameters for optimal grip and performance. The complete set includes pre-twisted wires, tensile prehank wire, U-shaped hanging ring, extension rod, heart-shaped tensioning ring, and all necessary connecting hardware.

Applications

Prestranded Suspension Clamps for OPGW are widely used in:

• High-voltage transmission lines (35 kV and above) for secure OPGW suspension at tensile and angle towers.
• Overhead ground wire installations in power utilities and smart grid projects.
• Long-span aerial fiber optic networks where high mechanical reliability and vibration control are essential.

Packaging

Products are supplied as complete matched sets and generally packed in standard wooden cases with pallets when required, or customized according to customer specifications.

Prestranded Suspension Clamp For OPGW Optical Cable offers a reliable, high-strength, and easy-to-install solution for suspending OPGW cables, ensuring mechanical integrity, vibration resistance, and uninterrupted optical communication in demanding transmission line environments.
