The unique all-dielectric and self-supporting nature of ADSS (All-Dielectric Self-Supporting) cables necessitates specialized stringing equipment designed to protect the cable's optical fibers and maintain its integrity throughout the installation process. Our comprehensive one-stop supply includes all essential equipment for ADSS installation:

I. Core Tension Stringing Equipment:

• 1. Hydraulic Pullers:

  • Function: Provide the controlled pulling force to string the ADSS cable from the reel through the stringing blocks.

  • Key Features: Must have precise digital tension control systems with a dynamometer to ensure the cable's Maximum Allowable Pulling Tension (MAPT) is never exceeded. They should also feature smooth-grooved bullwheels (often lined with durable, non-abrasive material) to prevent damage to the ADSS cable jacket.

  • Our Offering: Our range of hydraulic pullers offers the necessary power and precision for various ADSS cable sizes and span lengths, ensuring consistent tension control.

• 2. Hydraulic Tensioners:

  • Function: Apply continuous back tension to the ADSS cable as it's being paid out, preventing it from touching the ground, sagging excessively, or running uncontrolled.

  • Key Features: Similar to pullers, they require precise tension control and smooth, protective bullwheel linings.

  • Our Offering: Our tensioners work in perfect synchronization with our pullers to maintain optimal tension throughout the entire stringing operation, crucial for ADSS.

• 3. Puller-Tensioner Machines:

  • Function: Combined units that offer both pulling and tensioning capabilities from a single machine, providing operational flexibility and efficiency, particularly for complex or urban installations.

II. Specialized ADSS-Specific Accessories:

• 1. ADSS Stringing Blocks (Pulleys):

  • Function: Guide the ADSS cable along the span and around tower structures without exceeding its minimum bending radius or causing jacket damage.

  • Key Features: Absolutely critical. They must have large diameter sheaves (typically much larger than for conventional conductors, often 20-30 times the ADSS cable diameter) to prevent optical fiber stress. The grooves must be wide, smooth, and lined with highly protective, non-abrasive materials (e.g., polyurethane, neoprene) to prevent crushing, abrasion, or nicks to the all-dielectric jacket.

  • Our Offering: We provide a variety of ADSS-specific stringing blocks, meticulously designed for various cable diameters and span lengths, ensuring complete cable protection.

• 2. Non-Rotating Pulling Ropes:

  • Function: Essential for ADSS. These ropes (e.g., high-strength synthetic or braided steel) prevent torque from being transferred to the ADSS cable, which could induce twist and damage the internal fibers.

• 3. Anti-Twisting Devices (Swivels):

  • Function: Heavy-duty, ball-bearing swivels inserted between the pulling grip and the pulling rope to absorb any torsional forces, preventing the ADSS cable from twisting as it is pulled.

• 4. ADSS Pulling Grips (Stockings/Socks):

  • Function: Specifically designed to distribute the pulling force uniformly over a larger surface area of the ADSS cable, minimizing stress concentration on the jacket and internal strength members. They typically have a long, flexible, and often double-layered mesh design.

• 5. Cable Reel Stands/Trailers:

  • Function: Robust, high-capacity stands capable of safely unwinding large and heavy ADSS reels while maintaining controlled back tension.

• 6. Down-lead Clamps and Suspension/Dead-End Hardware:

  • Function: Specialized hardware used to secure the ADSS cable to the pole/tower, guide it down to splice points, and terminate it at dead-end structures. This hardware is often preformed or designed with elastomeric inserts to avoid crushing the ADSS jacket.

  • Our Offering: We supply a full range of compatible ADSS hardware to complement our stringing equipment.

III. Safety and Support Equipment:

• 1. Communication Systems: Reliable two-way communication (radios, headsets) between puller/tensioner operators and tower crews is paramount.

• 2. Sagging Tools: Optical or laser sagging tools for accurate sag measurement and adjustment.

• 3. Safety Gear: Standard fall protection, insulated gloves (if working near energized lines), and general PPE.

By providing this full spectrum of specialized ADSS installation tools and equipment, we ensure that our clients can achieve safe, efficient, and damage-free deployments of their aerial fiber optic networks worldwide.
