Product Description
Double Sheave Stringing Block for Overhead Line Construction
Dual-pulley cable guide designed for transmission projects with precision-machined sheaves that reduce friction, improve cable alignment, and ensure smooth, safe stringing operations.
Product Overview
The Double Sheave Stringing Block is a durable, high-efficiency pulley tool engineered for guiding conductors, OPGW, ADSS, and communication cables during overhead transmission line construction. This dual-pulley block is widely used by power utility companies, EPC contractors, and line construction teams for 11kV-500kV transmission projects.
What Is a Double Sheave Stringing Block?
A cable-guiding pulley equipped with two sheaves to support and guide conductors during stringing or sagging work. The dual-sheave design offers improved load distribution, smoother running, and reduced conductor wear, making it ideal for multi-layer cable pulling or heavier loads.
Key Features
- Dual Sheave Design: Two balanced sheaves for smoother cable entry and reduced tension, suitable for single or bundled conductors
- High-Strength Materials: Aluminum alloy or nylon sheaves available - lightweight, corrosion-resistant aluminum and wear-resistant nylon for fiber optic cables
- Robust Frame Construction: Heavy-duty steel frame with anti-rust coating and high structural strength for long-term outdoor operation
- Smooth Ball-Bearing Operation: Precision bearings ensure low-friction rotation and enhance cable protection during stringing
- Versatile Hook Options: Hook type, clevis type, or swivel type compatible with various field applications
Advantages
- Excellent Cable Protection: Smooth sheave surfaces minimize abrasion and reduce conductor damage
- High Load-Bearing Capacity: Engineered for high-tension transmission line pulling operations
- Long Service Life: Corrosion-resistant materials ideal for harsh outdoor environments
- Flexible Configuration: Available in different sheave diameters and groove types for ACSR, AAAC, OPGW, ADSS, etc.
- Easy to Install & Operate: Lightweight structure for quick setup in the field
Applications
- Overhead transmission line construction (11kV to 500kV)
- Conductor stringing and sagging operations
- OPGW/ADSS cable installation
- Communication line projects
- Mountain, valley, and long-span power line stringing
- Electrical utility and EPC contractor field work
