Product Description
Heavy-Duty Aluminum Nylon Conductor Pulley Blocks
Professional stringing pulley blocks designed for double and triple bundled conductors (300-900mm²) with working load capacity of 40-105kN. Ideal for overhead transmission line construction projects.
Product Overview
Aluminum-Nylon Stringing Pulley Blocks are engineered for overhead transmission line construction, specifically designed for double and triple bundled conductors. With a working load range of 40-105kN, these pulley blocks ensure smooth conductor handling, reduced friction, and high reliability during stringing operations.
Widely used in 110kV-500kV line projects, they provide stable guiding and protection for conductors and OPGW during installation.
Product Definition
A Stringing Pulley Block is a wheel-based guiding device used during conductor installation to reduce friction and prevent conductor damage.
- Aluminum alloy frame for superior strength
- High-density nylon sheaves for minimal friction
- Compatible with two- or three-bundled conductors
Key Features
- Durable Aluminum Alloy Frame: Excellent strength-to-weight ratio, corrosion resistance, and long service life
- Nylon Sheave with Smooth Rotation: Low friction coefficient prevents scratching or deformation of conductors
- 40-105kN Working Load: Suitable for medium and heavy-duty line stringing operations
- Support for 2-3 Bundled Conductors: Stable guiding for double or triple conductor arrangements
- High-Quality Bearings: Ensures smooth rotation and reduces pulling resistance
- Optional Grounding Device / Lining Protection: Customizable based on project requirements
Product Advantages
- High Strength & Lightweight: Aluminum alloy housing provides rigidity while reducing overall weight
- Reduced Conductor Wear: Nylon groove protects the surface of conductors and OPGW
- Lower Friction, Higher Efficiency: Professional bearing design reduces pulling force requirements
- Broad Compatibility: Applicable for 300-900mm² conductors and 40-105kN hydraulic tensioners
- Reliable Performance: Stable structure ensures consistent performance under continuous load
Applications
- Overhead transmission line stringing (110kV-500kV)
- ACSR / AAAC / ACCC conductor installation
- Double or triple bundle conductor guiding
- OPGW & ADSS fiber optic cable stringing
- Tower-to-tower conductor pulling operations
