Product Description
Triple-Sheave Bundled Conductor Stringing Block
Professional three-wheel pulley system designed for guiding and supporting bundled conductors during overhead transmission line construction operations.
Product Overview
The Triple-Sheave Bundled Conductor Stringing Block is engineered for medium- to high-voltage transmission line construction, featuring three large-diameter sheaves that ensure smooth conductor passage with minimal friction. This heavy-duty block is specifically designed for double or triple bundled ACSR, AAAC, and ACCC conductor installations.
Product Definition
A specialized rotating sheave device used to guide conductors during installation, featuring three independent sheaves within a reinforced frame structure. Compatible with various bundle configurations and conductor sizes, commonly deployed with hydraulic pullers, tensioners, and pilot rope systems in transmission line projects.
Key Features
- Triple-Sheave Configuration: Supports double- or triple-bundled conductors with stable guiding throughout the stringing process
- Heavy-Duty Frame Structure: Engineered for long-span, high-tension, and demanding field environments
- Low-Friction Bearings: Ensures smooth rotation, reduces pulling force, and improves construction efficiency
- Multiple Sheave Material Options: Aluminum, nylon, or rubber-lined grooves to match conductor protection requirements
- Customizable Groove Size: Groove diameter, width, and spacing can be tailored to specific conductor bundle specifications
Product Advantages
- Conductor Surface Protection: Reduced friction and optimized groove shape minimize scratches and bending stress
- High-Voltage Line Reliability: Commonly used in 110kV, 220kV, 330kV, and 500kV transmission lines
- Bundled Conductor Compatibility: Efficient for 2-bundle and 3-bundle configurations based on project design
- Extended Service Life: Sealed bearings and durable frame ensure consistent performance in field conditions
- Equipment Integration: Works seamlessly with standard line construction equipment and accessories
