Stringing bundled conductors (multiple conductors per phase) is significantly more complex than stringing a single conductor and requires specialized equipment to maintain the bundle's integrity and spacing:

• Running Boards (Conductor pulling grips): Instead of single-OHTLstringingequipment.com/Conductor-Grips--Clamps.html target='_blank'>Conductor Grips, a specialized running board is used to connect all conductors in the bundle to the pulling rope. These boards ensure that all conductors are pulled simultaneously and evenly, preventing twisting or unequal tension distribution within the bundle. Our running boards are designed for various bundle configurations (e.g., two, three, or four conductors).

• Multi-Groove OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks: Unlike single-groove blocks, multi-groove Stringing Blocks are essential. Each groove is designed to cradle an individual conductor within the bundle, maintaining the precise spacing and preventing the conductors from rubbing against each other or tangling during the pull. These blocks typically feature specialized non-abrasive liners to protect the conductor surfaces.

• Bundle Spacers: After stringing, bundle spacers are installed at regular intervals along the span to maintain the precise geometric configuration and electrical spacing between the conductors within the bundle. While not stringing equipment per se, their installation is a critical follow-up step directly related to bundle stringing.

• Higher Capacity Equipment: Bundled conductors are heavier and create more drag, often requiring pullers and Tensioners with higher pulling force and tensioning capacities compared to single-conductor stringing.

Our comprehensive range includes all the specialized equipment necessary for efficient and safe bundled conductor tension stringing, from robust running boards and multi-groove blocks to high-capacity hydraulic puller-Tensioners.
