Prestranding Tension Clamp for ADSS Cable

Pre-Twisted Tension Set for ADSS Cables (also known as Preformed Tension Clamp, Helical Dead-End Clamp, or Prestranding Tension Clamp) is a high-performance overhead line fitting specifically engineered for terminating and tensioning All-Dielectric Self-Supporting (ADSS) fiber optic cables on transmission towers and utility poles. Utilizing advanced helical pre-twisted armor rod technology, this tension set securely grips the cable, distributes mechanical loads evenly, and provides effective vibration damping while eliminating harmful stress concentrations that could damage optical fibers.

Key Features and Advantages

• Stress-Free Cable Protection: The pre-twisted helical design ensures uniform gripping without point loading, preserving the cable’s bending radius and optical performance.
• Excellent Mechanical Performance: High break strength and reliable grip strength make it suitable for long-span and high-tension applications.
• Easy & Rapid Installation: Preformed components allow quick hand application without special tools, significantly reducing installation time on site.
• Superior Vibration Damping: Helical armor rods effectively mitigate aeolian vibration and fatigue, extending cable service life.
• Corrosion Resistance & Durability: Manufactured from high-quality aluminum alloy armor rods and galvanized steel hardware for outstanding weather and UV resistance.
• Quality Certified: Produced under ISO9001:2008 and ROHS standards.

These tension sets are available in both single-layer and double-layer configurations to meet different span and tension requirements.

Main Components (Typical Assembly)

• Tension pre-twisted wire
• U-shaped shackle
• Heart-shaped tension ring
• Extension rod (for double-layer sets)
• Armor rods (inner and outer layers in double-layer designs)

The complete set is supplied as a matched assembly for optimal performance.
