100kN Balancing Running Board for Triple-Bundle Conductors | Heavy-Duty Line Stringing Guide Tool
The 100kN Balancing Running Board is a high-strength guiding tool designed for three-bundle conductor stringing in overhead transmission line construction. With its robust 100kN load capacity, this running board ensures stable alignment, balanced tension distribution, and smooth passage of bundled conductors through stringing blocks. Engineered for high-voltage projects, it provides excellent reliability and safety during conductor installation.
A balancing running board is a specialized tool used during bundle conductor installation to maintain equal spacing, guide multiple subconductors, and ensure they pass safely through pulleys and towers. Its symmetrical design prevents conductor overlap, twisting, or contact, making it essential for double-bundle and triple-bundle stringing operations.
Rated load capacity: 100kN for heavy-duty line construction
Designed for triple-bundle conductors (three subconductors)
Balancing structure maintains equal spacing across all subconductors
High-strength alloy steel frame ensures long service life
Smooth, low-friction rollers guide conductors through blocks with minimal wear
Corrosion-resistant surface suitable for outdoor and high-voltage environments
Universal connection points compatible with most stringing equipment
Precision-machined guide rings prevent conductor collision or deformation
Ensures precise conductor alignment during pulling operations
Prevents rubbing, twisting, or entanglement of subconductors
Reduces friction and mechanical stress, extending conductor lifespan
Improves construction efficiency—ideal for long-span stringing
Enhances safety for workers and equipment in high-voltage projects
Suitable for 220kV, 400kV, 500kV, and 750kV line construction
This 100kN triple-conductor running board is widely used in:
High-voltage and extra-high-voltage transmission line stringing
Triple-bundle conductor installation
Mountain and long-span line pulling
Utility grid construction and maintenance
Conductor guiding through large diameter pulleys
Power transmission EPC projects, national grid installations
