Collier de suspension pré-câblé pour câble optique OPGW | Support de suspension à armature hélicoïdale préformée

Le collier de suspension pré-câblé pour câble optique OPGW (également appelé collier de suspension préformé pour OPGW, collier de suspension à armature hélicoïdale ou collier de suspension pré-torsadé) est un accessoire hélicoïdal pré-câblé haute performance conçu pour suspendre les câbles OPGW (Optical Fiber Composite Overhead Ground Wire) sur les pylônes de transport d'énergie, notamment sur les pylônes à traction ou inclinés. Ce collier spécialisé assure une protection fiable et un amortissement auxiliaire tout en éliminant les concentrations de contraintes nuisibles, garantissant ainsi le maintien des performances mécaniques et optiques optimales du câble sous charges dynamiques.

Principales caractéristiques et avantages

• 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.
• Amortissement des vibrations supérieur: Effectively suppresses aeolian vibration and dynamic stresses caused by wind, enhancing cable fatigue resistance and service life.
• Installation facile et rapide: 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.
• Certifié de qualité: Produced under ISO9001:2008 et 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.

Conditionnement

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