What is a stringing block?

Stringing block is a commonly used device in power construction. Cables pass through the stringing block for various operations. Stringing block is usually composed of wheels and steel frames. The wheels are divided into nylon wheels, aluminum wheels, and rubber-coated aluminum wheels. Most stringing blocks usually have only one wheel, but some stringing blocks have two or even three wheels, which are the different functions of stringing blocks. There are many types of stringing blocks, some are suitable for ground construction, some are suitable for steering, and some are suitable for high-altitude operations. Stringing blocks are usually used in groups, and the capacity of a stringing block is limited. Stringing blocks can also be distinguished by wires, some are suitable for ordinary wires, and some are suitable for OPGW wires. The size of the stringing block that needs to be selected often depends on the diameter of the wire used. Before purchasing a stringing block, you need to know the diameter and rated load of the wire used in the construction, whether you need to use nylon wheels or aluminum wheels, and whether you need single wheels or multiple wheels. As long as you understand these issues, you can easily find the products that meet your specifications.
