The 7 Sheaves MC Nylon Large Diameter Stringing Blocks are engineered for transmission line construction, overhead conductor stringing, and cable pulling applications. Featuring 508-916mm large diameter sheaves, 20-150kN rated load capacity, and a 7-sheave structure, these cable pulling blocks deliver stable support for multi-conductor stringing operations. The MC nylon sheaves significantly reduce conductor wear and friction during extended pulling tasks.
The 7 Sheaves MC Nylon Stringing Blocks effectively address these challenges through:
| Parameter | Value | Engineering Significance |
|---|---|---|
| Product Name | 7 Sheaves Stringing Blocks | For multi-conductor stringing |
| Sheave Diameter | 508-916 mm | Reduces conductor bending stress |
| Rated Load | 20-150 kN | Suitable for heavy-duty pulling |
| Number of Sheaves | 7 Sheaves | Supports bundle conductor installation |
| Sheave Material | MC Nylon | Reduces conductor wear |
| Applicable Conductor | ACSR400-720 / Customizable | Suitable for transmission line projects |
| Structure Type | Multi Sheave | Improves load distribution |
| Application | Transmission Line / Cable Pulling | Used for power construction |
The stringing block guides conductors through seven rotating MC nylon sheaves during pulling operations. The large diameter sheaves minimize bending stress on the conductor, while the 7-sheave structure ensures even load distribution, enhancing stability during multi-conductor stringing. The MC nylon material significantly reduces friction and protects the conductor surface throughout the operation.
Based on conductor size:
For medium conductors, choose 508mm or 660mm sheaves.
For larger conductors, choose 822mm or 916mm sheaves.
Based on load requirement:
For standard projects, 20-60kN may be suitable.
For heavy-duty projects, choose 100-150kN rated load.
Based on conductor protection:
Choose MC nylon sheaves to reduce cable wear and protect the conductor surface.
Based on construction method:
For bundle conductor stringing, 7 sheaves provide better stability and load distribution.
