Corrosion Resistant Head Board for Four Bundle Conductors with 130-320KN Rated

Product Specification

• Maintains Precise Square Configuration:​ The fundamental role of this head board is to preserve the exact geometric spacing of the four sub-conductors in a stable square formation. This precise configuration is crucial for maximizing the electrical capacity of the line while optimizing its aerodynamic performance to minimize wind-induced vibration and audible noise. The design ensures consistent spacing throughout the pulling process, preventing conductor clash and preserving the integrity of the bundle.
• Even Tension Distribution:​ A key engineering achievement is the ability to distribute the immense pulling force equally among all four conductors. This balanced load sharing is vital to prevent uneven sagging and to ensure that no single conductor is subjected to excessive stress. The head board's design guarantees synchronized tensioning, which is essential for the mechanical and electrical performance of the completed line.
• Exceptional Load-Bearing Capacity:​ Manufactured from high-strength forged steel or special aluminum alloys, this head board is engineered to withstand the extreme forces involved in pulling heavy conductor bundles over long spans. Its robust construction features reinforced connection points and a rigid frame that resists deformation under the highest loads, ensuring reliable performance in the most demanding ultra-high-voltage projects.
• Superior Conductor Protection:​ The design incorporates smoothly contoured sheaves and contact surfaces that guide each conductor without causing abrasion, crushing, or scratches to the sensitive outer strands. This protection is crucial for maintaining the conductor's mechanical strength and electrical properties, preventing points of weakness that could lead to future failures in the transmission line.
• Enhanced Operational Safety:​ Handling four conductors simultaneously presents significant safety challenges. This head board provides a secure and controlled connection point that minimizes the risks associated with conductor whipping, snapping, or becoming uncontrolled during tensioning. Its reliable performance provides crews with the confidence to execute complex stringing operations safely.
• Maximum Installation Efficiency:​ Using a dedicated head board for four-bundle configurations represents the most efficient installation method. It allows all four conductors to be strung in a single, coordinated operation, dramatically reducing project timelines compared to sequential or individual conductor pulling methods. This efficiency translates into significant savings in labor, equipment usage, and overall project costs.
• Seamless System Integration:​ The head board is designed for full compatibility with standard stringing systems, including swivels, pulling grips, and tensioners. This interoperability ensures a smooth workflow from the reel to the dead-end structure, simplifying logistics and reducing setup time for the stringing crew.
• Durable and Low Maintenance:​ Built for rugged field use, the head board features corrosion-resistant materials and finishes that withstand harsh environmental conditions. Its durable construction requires minimal maintenance over an extended service life, making it a cost-effective investment for utility contractors specializing in high-capacity transmission lines.
• Proven Field Reliability:​ This equipment has been tested and proven in actual ultra-high-voltage projects worldwide. Its design incorporates lessons learned from field experience, ensuring that it meets the practical demands of modern transmission line construction and delivers reliable performance when it matters most.
