Double Pulley Optic Cable Replacer Anti-Lifting Hold Down Pulley Blocks For OPGW

The Model SHSS10 Anti-Lifting Hold Down Pulley Blocks are specialized pulley blocks designed specifically for OPGW (Optical Ground Wire) fiber optic cable stringing and installation. These blocks help prevent the cable from lifting or slipping during tensioning and pulling operations, ensuring safe and controlled handling of fiber optic cables.

Key Features:

• Anti-Lifting Hold Down Design
  The SHSS10 is engineered to securely hold down OPGW cables during stringing, preventing unwanted vertical movement or lifting of the cable under tension. This feature is critical for maintaining cable integrity and alignment on transmission towers or poles.

• Double Pulley Configuration
  Typically, the SHSS10 model includes two sheaves (pulleys), allowing smooth passage of the cable while distributing the load evenly. This reduces friction and potential damage to delicate fiber optic cables.

• Materials and Durability
  The pulley block is usually constructed from high-strength aluminum alloy or galvanized steel with corrosion-resistant coatings, suitable for outdoor environments and long-term use on power lines.
  Sheaves are often made from nylon or aluminum with sealed ball bearings, ensuring smooth rotation and minimal wear on the cable.

• Load Capacity
  While specific load ratings for the SHSS10 model are not detailed in the search results, similar anti-lifting pulley blocks for OPGW cables are designed for medium to heavy loads typical in fiber optic cable stringing, often rated around 10 kN or higher.

• Mounting and Installation
  The SHSS10 pulley block can be mounted securely on crossarms or tower structures, compatible with standard rigging hardware used in OPGW cable installation.

• 

Applications:

• Used extensively in OPGW fiber optic cable stringing and replacement on overhead power transmission lines.

• Ideal for preventing cable lifting and ensuring controlled tension during installation, which protects the fiber optic strands inside the cable.

• Suitable for use in various weather conditions due to corrosion-resistant materials.

Summary

The Model SHSS10 Anti-Lifting Hold Down Pulley Block is a durable, double-sheave pulley block designed to securely hold down OPGW fiber optic cables during stringing and tensioning operations. Its anti-lifting feature helps prevent cable displacement, protecting the fiber optic core from damage. Constructed from corrosion-resistant materials with smooth-rotating sheaves, the SHSS10 is well-suited for reliable, safe, and efficient OPGW cable installation on overhead power lines.
