SHDN660 Steel-Frame Single Conductor Stringing Block | 660mm Transmission Line Pulley
1. Overview
The SHDN660 Steel-Frame Single Conductor Stringing Block is designed for guiding and supporting conductors during overhead transmission line construction. With a durable steel frame and a 660mm diameter sheave, this model ensures smooth conductor passage, reduced friction, and reliable performance for medium- and high-voltage line projects.
It is widely used in 110kV–500kV transmission line stringing operations.
2. Product Definition
A stringing block is a pulley-type guiding tool used to support and direct conductors during line installation.
The SHDN660 model features:
3. Key Features
• 660mm Sheave Diameter
Provides a large guiding radius, reducing conductor bending stress and protecting the surface during pulling.
• High-Strength Steel Frame
Offers excellent load-bearing capacity and long-term durability in harsh construction environments.
• Low-Friction Smooth Bearings
Ensures efficient rotation, lowers pulling resistance, and improves stringing efficiency.
• Designed for Single Conductor
Suitable for ACSR, AAAC, ACCC, and similar conductor types.
• Customizable Groove & Hooks
Options include aluminum sheaves, nylon sheaves, grounding rollers, swivel hooks, and connection fittings.
4. Advantages
• High structural strength for overhead line work
The steel frame design provides enhanced rigidity and stability.
• Protects conductor surface during installation
Smooth sheave rotation reduces wear and prevents conductor scratching.
• Compatible with various stringing equipment
Works with hydraulic tensioners, pullers, pilot rope systems, and tower-mounted fittings.
• Reliable for long-span or mountain terrain projects
Stable performance under continuous load conditions.
• Long service life
Engineered for extended field use with minimal maintenance.
5.Applications
Suitable for:
Overhead transmission line stringing (110kV–500kV)
Single-conductor installation for ACSR, AAAC, ACCC
Pilot rope to conductor stringing transition
Tower-to-tower pulling operations
Mountain and long-span construction projects
