The 20kN OPGW cable pulley block is engineered for fiber optic cable stringing and optical ground wire installation in transmission line projects. This heavy-duty tool accommodates OPGW and fiber optic cables with maximum diameters up to 22mm.
As a robust stringing and cable pulling block, it facilitates smooth cable guidance during pulling operations, minimizes friction, and protects optical cable surfaces during overhead line construction.
Primary applications include transmission line installation, power line construction, OPGW replacement, and fiber optic cable pulling projects where secure cable guidance and stable operation are essential.
The 20kN OPGW cable pulley block delivers superior performance through:

| Applicable Cable | OPGW / Fiber Optic Cable | Used for optical ground wire installation |
| Function | Guiding / Pulling / Cable Protection | Reduces friction and cable surface damage |
| Application | Transmission Line Installation | Used in overhead power line construction |
| Customization | Available | Sheave size, material and frame type can be customized |
During transmission line installation, OPGW or fiber optic cables are positioned within the pulley block. As pulling commences, the sheave rotates with cable movement, guiding the cable along the designated route.
The pulley groove maintains proper cable positioning while smooth sheave rotation minimizes friction. This design prevents surface wear, cable twisting, and pulling resistance during overhead line construction.
For extended OPGW installations, multiple cable pulley blocks can be deployed at tower points, angle positions, or support locations to ensure smooth, controlled cable movement.
The 20kN rated load capacity makes this pulley block ideal for OPGW cable installation and transmission line construction where robust pulling support is essential.
Engineered for OPGW and fiber optic cables up to 22mm diameter, ensuring contractors select appropriate tools for optical ground wire projects.
The cable-guiding sheave minimizes friction and protects optical cable surfaces during pulling operations.
Structural design optimized for tower work, power line construction, transmission line installation, and OPGW replacement projects.
Sheave material, pulley size, frame structure, and mounting configurations can be customized according to specific cable types and site conditions.
For OPGW or fiber optic cables up to 22mm, this model is appropriate. Larger cable diameters require pulley blocks with expanded groove and sheave dimensions.
For standard optical cable operations, select rated load according to project tension requirements. Higher tension transmission line work benefits from the 20kN capacity for enhanced construction support.
For superior cable protection, nylon or rubber-lined sheaves are recommended. Harsh outdoor conditions warrant reinforced frames and durable sheave materials.
Standard OPGW pulley blocks suit straight-line sections. Tower or angle positions require appropriate mounting structures. Long-distance pulling operations utilize multiple stringing blocks to reduce friction and stabilize cable movement.
