The stringing block is a critical component in tension stringing, directly influencing conductor integrity. For sensitive conductors like HTLS or OPGW, the choice of stringing block is paramount:

• Lining Material: Traditional steel-lined blocks can damage the outer strands or specialized coatings of sensitive conductors. Our OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks for HTLS, ACCC, or OPGW conductors feature specialized liners made from high-molecular-weight polymers like polyurethane or robust nylon. These materials provide a low-friction, non-abrasive surface that prevents nicks, scratches, and deformation of the conductor's outer layers.

• Groove Design and Diameter: The groove must be precisely sized to cradle the conductor without pinching or allowing excessive movement. For larger or bundled conductors, multi-groove blocks or those with larger diameters are essential to maintain the conductor's natural bending radius and prevent kinking or stress concentrations.

• Bearing Quality: High-quality, sealed bearings ensure smooth rotation of the sheave, minimizing friction and preventing uncontrolled conductor movement, which is particularly important for maintaining consistent tension.

• Sheave Configuration: Depending on the project, specialized OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (e.g., those for vertical stringing, running boards for multiple conductors, or those with specific attachment methods) are chosen to ensure the conductor navigates obstacles and structures smoothly.

We offer a comprehensive range of high-quality stringing blocks engineered with these considerations in mind, ensuring optimal protection for all types of overhead conductors during installation.
