The 916mm diameter conductor stringing pulley block is a heavy-duty cable pulling tool designed for transmission line installation and overhead conductor stringing work. With a large diameter sheave, 20-150kN rated load options, and 1-9 sheave configurations, it provides stable support for high-voltage power line construction while reducing conductor bending stress and cable surface wear.
This series of stringing blocks and cable pulling blocks is suitable for ACSR conductors, large-diameter overhead cables, and multi-conductor stringing projects. The sheave material can be selected according to working conditions, including MC nylon, cast steel, or rubber-lined options.

During cable pulling or conductor stringing, the conductor passes through the rotating sheave of the pulley block. The 916mm large diameter sheave helps reduce bending pressure and allows the conductor to move more smoothly.
For multi-conductor projects, 3-sheave, 5-sheave, 7-sheave, or 9-sheave stringing blocks can distribute the load more evenly and improve stringing stability. Low-friction sheave material also helps reduce pulling resistance and protects the conductor surface during long-distance installation.
Based on conductor size: For large overhead conductors, choose 916mm diameter stringing blocks to reduce bending stress.
Based on pulling tension: For standard line work, select 20-60kN rated load. For heavy-duty transmission projects, select 100-150kN rated load.
Based on conductor quantity: For single conductor installation, choose 1 sheave structure. For bundled conductor stringing, choose 3 / 5 / 7 / 9 sheave structure.
Based on sheave material: For better cable protection, choose MC nylon sheave. For heavy load and tough working conditions, choose cast steel sheave. For special cable protection needs, choose rubber-lined sheave.
