About Bundled Conductor Headboard
Bundled Conductor Headboard
The headboards are designed in such a way that they can self adjust to a correct position while passing over aerial rollers, enabling the conductors to pass through the grooves of the sheaves. The hinged tail assembly, made up of forged links (UT tested), stabilizes the headboard against lateral lifting due to wind pressure. The load carrying members like balancing pulleys, having roller bearings for high load bearing capacity, are made of heat treated alloy steel, which makes

A Bundled Conductor Headboard is a specialized tool used in the installation of high-voltage transmission lines that feature multiple conductors per phase (e.g., 2, 3, or 4 bundled conductors). This headboard serves as a support and guide for these bundled conductors during the stringing process, preventing them from swaying or twisting and ensuring a smooth, controlled operation as they are pulled into position by stringing blocks. It's typically made of durable materials like forged steel and designed to accommodate a specific number of bundled conductors for tasks like maintenance and installation.
-
Stabilization:
The primary function of a bundled conductor headboard is to keep the multiple sub-conductors in a bundle stable and evenly spaced during the conductor stringing process.
-
Guidance:
It acts as a guide, ensuring that the bundled conductors are fed smoothly and without damage into the stringing blocks.
-
Protection:
By providing stable support and preventing swaying, the headboard indirectly protects the mid-span joints and the overall conductor integrity during installation.
-
Material:
Bundled conductor headboards are constructed from high-strength materials like forged steel to withstand the heavy loads and harsh conditions encountered during transmission line construction.
-
Specificity:
They are designed for a specific number of bundled conductors (e.g., headboards for 2-conductor, 3-conductor, or 4-conductor bundles), ensuring a proper fit and function.
-
High-Voltage Lines:
Bundled conductors are employed in Extra High Voltage (EHV) lines (typically 230 kV and above) to improve transmission efficiency by reducing inductance and minimizing corona discharge.
-
Stringing Operations:
The headboard is a crucial piece of equipment used in conjunction with other tools like stringing blocks, pilot wires, and come-along clamps for the proper installation and maintenance of these lines.
