Selecting the right stringing block is a critical decision that directly impacts the safety and efficiency of your project. As a leading manufacturer, we recommend considering three key factors:

1. Conductor Type & Size: Match the sheave groove and size to the specific conductor or cable you are stringing. Our blocks are designed to accommodate a wide range of ACSR and other conductors.

2. Application: The block type depends on your project. Single sheave blocks are used for single conductors, while three-sheave or five-sheave blocks are specifically designed for stringing bundled conductors.

3. Working Load: The rated load (KN) of the stringing block must exceed the maximum pulling tension anticipated during the stringing operation.

At Ningbo Changshi, we provide a variety of high-quality blocks to meet every project requirement, with options for different materials and configurations.
