High-Temperature Low-Sag (HTLS) conductors are a game-changer for transmission lines, allowing for increased power capacity on existing structures, but they significantly impact stringing practices and require specialized equipment:

• Increased Capacity on Existing ROWs: HTLS conductors can operate at much higher temperatures and carry significantly more current than traditional ACSR (Aluminum Conductor Steel Reinforced) conductors without exceeding sag limits. This is crucial for "reconductoring" projects, upgrading lines without building new towers or acquiring new rights-of-way.

• Sensitive Construction Requirements: The core of HTLS conductors often consists of composite materials (e.g., carbon fiber) or special alloys that are more sensitive to bending, crushing, and abrasion during installation than traditional steel cores. This necessitates extreme care.

• Specialized OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (Sheaves): Our stringing blocks for HTLS conductors feature:

  • Non-Metallic Liners: Typically made from high-molecular-weight polymers like polyurethane or robust nylon to prevent scratching, denting, or damaging the outer strands of the conductor or its sensitive core.

  • Larger Diameter Grooves: To ensure the conductor maintains its natural bending radius and avoids excessive stress points.

• Precision Tensioning: Due to their low-sag properties and sensitivity, HTLS conductors require even more precise tension control during stringing to achieve the exact design sag. Our hydraulic Tensioners are engineered for this high degree of accuracy and offer continuous, smooth tension application to prevent uncontrolled slippage or sudden jerks.

• Controlled Pulling: Pulling operations must be smooth and consistent to avoid "snatching" or overstressing the conductor. Our hydraulic pullers provide precise speed and force control.

• Specialized Grips and Running Boards: pulling grips must distribute force evenly across the conductor's surface, and running boards for bundled HTLS conductors must be specifically designed to handle their unique characteristics.

We provide the complete suite of specialized tension Stringing Equipment—from our advanced pullers and tensioners to the critical HTLS-compatible stringing blocks and accessories—ensuring the safe, efficient, and damage-free installation of these high-performance conductors.
