This is a critical question for grid modernization projects. Modern HTLS conductors cannot be handled by standard equipment due to their composite cores (carbon or composite fiber) and softer aluminum outer strands. Using the wrong equipment will cause irreparable damage.

Ningbo Changshi has engineered specific solutions for these advanced conductors:

• Larger Diameter Bull-Wheels: Our puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners designed for HTLS feature bull-wheels with a much larger diameter. This wider bending radius prevents the sensitive core from cracking or breaking under tension.

• Specialized Lining: The grooves of our bull-wheels are lined with high-density nylon or polyurethane sectors that cushion the soft aluminum strands, preventing scratches and deformation.

• Precision Tension Control: Our hydraulic systems offer extremely fine-tuned, stable tension control, which is essential for preventing the core and strands from separating or being over-stressed during the stringing process.

• Special OHTLstringingequipment.com/Conductor-Grips--Clamps.html target='_blank'>Conductor Grips: We provide specialized "core-gripping" or "full-tension" grips designed specifically for ACCC® and other composite core conductors that safely hold the conductor without compromising its integrity.

Before starting any HTLS project, it's vital to consult with us to ensure you have a fully compatible and certified equipment set.
