Four-Bundle Conductor Stringing Running Board for EHV/UHV Lines

Four-Bundle Conductor Running Board: Precision & Control for Extra-High Voltage (EHV) and Ultra-High Voltage (UHV) OHTL Stringing

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we are at the forefront of providing cutting-edge solutions for the most technically demanding and largest-scale overhead transmission line (OHTL) construction projects globally. Our Four-Bundle Conductor Running Board is a state-of-the-art, meticulously engineered piece of equipment specifically designed to facilitate the perfectly synchronized, smooth, and precisely balanced pulling of four bundled conductors across spans during extra-high voltage (EHV) and ultra-high voltage (UHV) tension stringing operations. As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for a wide array of tools and equipment for power lines, and this high-capacity running board exemplifies our unwavering commitment to extreme precision, operational safety, and unparalleled reliability for ensuring the success and long-term integrity of your most critical OHTL infrastructure.

EHV and UHV transmission lines often utilize four or more sub-conductors per phase to achieve optimal electrical performance, reduce corona losses, and manage high current capacities. Stringing these large, intricate four-conductor bundles requires not only immense pulling capacity but also absolute, uncompromised precision in distributing tension equally among all sub-conductors to prevent damage and ensure proper spacing. Our Four-Bundle Conductor Running Board is ingeniously designed for this challenge. It features an advanced, robust balancing clevis system that ensures the pulling force is distributed perfectly to each of the four conductors, eliminating any differential tension, twisting, or birdcaging. This critical feature prevents costly conductor damage and significantly enhances the safety, efficiency, and ultimate success of large-scale EHV/UHV line installations, securing the integrity of these vital components.

Product Features & Benefits:

• Optimized for Four-Bundle Conductors: Specifically configured with four individual conductor attachment points and an advanced balancing system, making it the ideal solution for complex four-bundle conductor configurations in EHV/UHV lines.

• Precision Balancing System: Incorporates a sophisticated clevis and pivot mechanism that ensures the pulling force is distributed uniformly and precisely to each of the four conductors, preventing uneven tension and safeguarding conductor integrity.

• Prevents Conductor Damage: The balanced pulling action, combined with smooth, integrated conductor paths, prevents critical issues like birdcaging, kinking, or severe strand deformation, preserving the long-term performance of high-value conductors.

• High Load Capacity & Robustness: Engineered from premium, high-strength forged steel or specialized alloys, designed to safely withstand the immense pulling forces and continuous demands encountered during EHV/UHV stringing.

• Smooth Conductor Passage: Designed to glide effortlessly through large, multi-sheave Stringing Blocks, minimizing friction and abrasion on the conductors throughout the entire pulling operation.

• Enhanced Operational Efficiency: Enables simultaneous pulling of all four conductors, dramatically reducing stringing time and labor costs compared to sequential methods.

• Seamless System Integration: Designed to integrate flawlessly with high-capacity Tensioners, pullers, and Stringing Blocks used in large-scale OHTL construction.

• Exceptional Durability & Longevity: Built for continuous, heavy-duty use in harsh outdoor environments, ensuring extended service life and consistent, reliable performance.

• Corrosion Resistance: Typically finished with hot-dip galvanization or durable industrial coatings, providing excellent protection against rust and environmental degradation.

Product Applications:

Our Four-Bundle Conductor Running Board is an indispensable tool for the most critical and complex operations involving four-bundle conductors on overhead transmission lines:

• EHV/UHV line stringing: Essential for the initial pulling and installation of new four-bundle conductor phases on extra-high and ultra-high voltage transmission towers.

• Major Re-conductoring Projects: Ideal for efficiently and safely replacing existing four-bundle conductors on critical transmission infrastructure.

• Complex Terrain & Long-Span Stringing: Provides the necessary control and balanced pulling for conductors traversing vast distances, challenging landscapes, river crossings, or mountainous regions.

• High-Capacity Bundle Management: Crucial for projects requiring the utmost precision and safety when handling multiple large conductors per phase.

• Tension Sagging & Adjustment: Facilitates the accurate adjustment of sag for four-bundle conductors, ensuring adherence to stringent electrical and mechanical design specifications.

• Connection to Powerful Pulling Equipment: Serves as a robust and precisely balanced interface between heavy-duty pulling ropes and the four individual conductors of the bundle.
