Product Description

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.

What Is a Balancing Running Board?

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.

Key Features

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

Advantages

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

Applications

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

Frequently Asked Questions

What conductor types can this running board handle?

It is designed for three-bundle conductors typically used in 220kV to 750kV transmission projects.

Why is the balancing design important?

It keeps subconductors equally spaced, preventing twisting, overlap, and mechanical damage during stringing.

Is it compatible with other stringing tools?

Yes. It works with most standard pulleys, gin poles, tensioners, and hydraulic pullers.

What is the maximum load capacity?

The running board supports 100kN, suitable for heavy-duty long-span operations.

Can it be customized?

Yes—subconductor spacing, roller material, and frame dimensions can be customized for specific projects.
