ADSS-001-2 Pre - Twisted tension clamp for optical fiber cable

1. Structural Composition

Generally composed of inner strands, outer strands, a heart-shaped ring, and an embedment ring. The inner strands are tightly wound around the optical fiber cable, while the outer strands wrap around the inner strands, connecting to utility poles or other fixing devices through the heart-shaped ring and embedment ring. This layered structure ensures a secure grip on the cable and reliable load transmission to the supporting structure.

2. Material Characteristics

Inner/Outer Strands: Typically made of high-strength aluminum alloy or stainless steel, offering high tensile strength and corrosion resistance. These materials withstand long-term outdoor exposure while maintaining mechanical integrity.

Heart-shaped Ring & Embedment Ring: Usually constructed from hot-dip galvanized steel or aluminum alloy, capable of bearing significant tensile forces. The galvanization process provides an anti-corrosion barrier, ensuring durability in harsh environments.

3. Pre-twisted Design

The strands are pre-formed into a specific shape and size before installation, allowing them to closely conform to the surface of the optical fiber cable and evenly distribute mechanical stress. This design eliminates concentrated pressure points, reducing the risk of cable damage and enhancing the clamp’s grip strength. The pre-twisted structure also simplifies installation, as the strands naturally wrap around the cable without requiring specialized tools or complex adjustments.

1. High Grip Strength

Capable of providing reliable grip force to ensure the optical fiber cable does not slip or detach under significant tension, guaranteeing the safe and stable operation of the line. The interlocking design of pre-formed strands and the friction-enhanced contact surface create a robust mechanical connection, even in high-tension scenarios such as long-span installations or cable terminations.

2. Cable Protection

The pre-twisted structure evenly distributes mechanical stress, preventing concentrated forces on the optical fiber cable while providing excellent protection to reduce the risk of abrasion and damage. The helical wrapping of strands conforms to the cable’s curvature, minimizing sheath deformation and fiber stress—a critical benefit for fragile optical fibers sensitive to mechanical strain.

3. Convenient Installation

The installation process is relatively simple and requires no special tools, improving construction efficiency and reducing installation time. The pre-formed strands can be quickly wrapped around the cable by hand, and the clamp is secured through standardized fittings, making it suitable for both field installations and maintenance operations, even in hard-to-reach locations.

1. Tension Anchoring

Used to fix ADSS (All-Dielectric Self-Supporting) optical fiber cables on tension towers or terminal towers, bearing the cable’s tensile force to maintain stability within the tension section. This function is critical for preventing cable sagging or disconnection at tower endpoints, ensuring the mechanical integrity of the overhead optical cable system.

2. Tension Transfer

Transmits the tensile force of the optical fiber cable to the tower or other fixed structures through the clamp, achieving effective tension transfer and maintaining the cable’s stable mechanical performance. The clamp’s robust design efficiently distributes tension across the connection point, preventing stress concentrations that could damage the cable or supporting structures.

3. Line Connection

As a key component in ADSS optical fiber cable lines, it enables reliable connection between tension sections, ensuring the integrity and reliability of the entire optical communication system. By securely terminating and linking cables at tower locations, the clamp maintains signal continuity and mechanical stability, supporting seamless data transmission across long-distance or complex terrain networks.
