Six/Eight Bundle Conductor Running Board for Ultra-High Voltage (UHV) Lines

Six/Eight Bundle Conductor Running Board: The Ultimate Solution for Ultra-High Voltage (UHV) Transmission line stringing

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we are at the absolute forefront of providing state-of-the-art solutions for the most technically demanding and largest-scale overhead transmission line (OHTL) construction projects globally, particularly those involving Ultra-High Voltage (UHV) systems. Our Six/Eight Bundle Conductor Running Board is a pinnacle of engineering, meticulously designed to facilitate the perfectly synchronized, smooth, and precisely balanced pulling of six or eight bundled conductors across spans during the most complex 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 ultra-high capacity running board exemplifies our unwavering commitment to extreme precision, unparalleled operational safety, and absolute reliability for ensuring the success and long-term integrity of the world's most critical UHV OHTL infrastructure.

UHV transmission lines (typically 1000 kV and above) utilize extremely large conductor bundles (six, eight, or more sub-conductors per phase) to manage immense power loads, minimize electrical losses, and optimize performance. Stringing these massive, intricate bundles demands equipment with not only colossal pulling capacity but also an unprecedented level of precision in distributing tension equally among all sub-conductors to prevent any form of damage. Our Six/Eight Bundle Conductor Running Board is ingeniously engineered for this supreme challenge. It features a highly advanced, robust, and articulated balancing clevis system that ensures the pulling force is distributed perfectly and simultaneously to each of the six or eight conductors. This eliminates any differential tension, twisting, or localized stress, which could lead to severe conductor damage (like birdcaging or kinking) that is unrecoverable. This superior design translates directly into a safer, more efficient, and ultimately flawless stringing process for the largest, most critical UHV line installations, securing the integrity of these vital components from the outset.

Product Features & Benefits:

• Ultimate Multi-Bundle Capacity: Specifically engineered for the most demanding UHV applications, accommodating six or eight individual conductors per bundle, a critical feature for high-capacity lines.

• Hyper-Precision Balancing System: Incorporates a sophisticated, multi-articulated clevis and pivot mechanism that ensures pulling force is perfectly and equally distributed to every single conductor in the bundle, eliminating differential tension and safeguarding conductor integrity.

• Maximum Conductor Protection: The balanced pulling action, combined with smooth, integrated conductor paths and optimized geometry, actively prevents critical issues like birdcaging, kinking, crushing, or severe strand deformation, preserving the long-term performance and lifespan of extremely high-value conductors.

• Extreme Load & Robustness: Manufactured from the highest-grade, heavy-duty forged steel or specialized alloys, designed to safely withstand the immense pulling forces (often exceeding 200kN or more total WLL) and continuous, rigorous demands of UHV stringing operations.

• Effortless Passage Through Blocks: Engineered with precision to glide seamlessly through large, multi-sheave Stringing Blocks and over tower structures, minimizing friction and abrasion on the conductors throughout the entire pulling operation.

• Unparalleled Operational Efficiency: Enables simultaneous pulling of all six or eight conductors, dramatically reducing stringing time, labor costs, and overall project duration for massive infrastructure projects.

• Seamless System Integration: Designed to integrate flawlessly with the most powerful and advanced Tensioners, pullers, and Stringing Blocks used in large-scale UHV OHTL construction.

• Exceptional Durability & Longevity: Built for continuous, heavy-duty use in the harshest outdoor environments, ensuring extended service life and consistent, reliable performance on mission-critical projects.

• Superior Corrosion Resistance: Finished with advanced galvanization or industrial-grade protective coatings, providing outstanding resistance against rust, corrosion, and environmental degradation, crucial for long-term reliability.

Product Applications:

Our Six/Eight Bundle Conductor Running Board is an indispensable tool for the most critical and complex operations involving six or eight bundle conductors on overhead transmission lines:

• UHV Transmission line stringing: Essential for the initial pulling and installation of new six or eight bundle conductor phases on Ultra-High Voltage (UHV) transmission towers.

• Major UHV Re-conductoring Projects: Ideal for efficiently and safely replacing existing large bundle conductors on vital UHV infrastructure.

• Cross-Country & Inter-Regional Grid Development: Provides the necessary control and balanced pulling for conductors traversing vast distances and complex, challenging landscapes.

• High-Capacity Bundle Management: Crucial for projects demanding the utmost precision, safety, and efficiency when handling numerous large conductors per phase.

• Precision Sagging & Tensioning: Facilitates the accurate adjustment of sag for six or eight bundle conductors, ensuring strict adherence to highly sensitive electrical and mechanical design specifications for optimal UHV performance.

• Connection to Ultimate Pulling Equipment: Serves as the robust and precisely balanced interface between the most powerful pulling ropes and the multiple individual conductors of the bundle.
