508mm MC nylon sheave large diameter stringing blocks are engineered for overhead transmission line construction and conductor pulling applications. Featuring 508mm large diameter sheaves, 20-60kN rated load capacity, and 1/3/5 sheave configurations, these cable pulling blocks provide stable conductor support while minimizing bending stress and cable surface wear.
The MC nylon sheave design offers superior conductor protection during stringing operations, particularly for medium-size conductors such as ACSR400 in power line installation projects.
508mm Large Diameter Design → Reduces conductor bending stress
MC Nylon Sheave → Minimizes cable wear and protects conductor surface
1/3/5 Sheave Options → Suitable for single, twin and bundled conductor stringing
20-60kN Rated Load → Supports medium-duty transmission line construction
Customizable Structure → Adapts to diverse power construction requirements
| Parameter | Value | Engineering Significance |
|---|---|---|
| Sheave Diameter | 508mm | Reduces conductor bending stress |
| Sheave Dimension | Φ508*Φ408*75mm | Suitable for medium-size conductor stringing |
| Rated Load | 20 / 40 / 60kN | Covers single and multi-sheave pulling work |
| Number of Sheaves | 1 / 3 / 5 | Supports single, twin or bundled conductor installation |
| Sheave Material | MC Nylon | Reduces cable wear and friction |
| Applicable Conductor | ACSR400 | Suitable for medium transmission line conductors |
| Conductor Diameter | 17-25mm | Common range for overhead line construction |
| Application | Transmission Line / Cable Pulling | Used for power construction projects |
| Model | Sheaves | Rated Load | Weight | Sheave Material | Recommended Use |
|---|---|---|---|---|---|
| SHDN508 | 1 | 20kN | 16kg | MC Nylon | Single conductor stringing |
| SHSQN508 | 3 | 40kN | 38kg | MC Nylon | Twin / multi-conductor stringing |
| SHWQN508 | 5 | 60kN | 70kg | MC Nylon | Bundled conductor construction |
The stringing block guides conductors through rotating MC nylon sheaves during pulling operations. The 508mm large diameter sheave significantly reduces bending stress, while the nylon material minimizes friction and provides superior conductor surface protection.
For single conductor construction, a 1-sheave block is typically employed. For bundled conductor or multi-conductor applications, 3-sheave or 5-sheave stringing blocks deliver enhanced load distribution and pulling stability.
