100kN Balancing Running Board for Triple-Bundle Conductors | Heavy-Duty Line Stringing Guide Tool
Product Overview
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? (Definition)
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.
