Headline: HTLS & Composite-Core Conductors: What Field Teams Must Know for Safe Stringing

News Body:
High-Temperature Low-Sag (HTLS) and composite-core conductors (e.g., ACCC) are increasingly used to upgrade corridor capacities without new towers. However, their different mechanical and thermal behaviors mean standard stringing procedures may not apply.

Field best practices include:

• Sheave selection: use larger-diameter sheaves to reduce bending stress on composite cores.

• Controlled tension profiles: follow manufacturer tension curves and avoid rapid load changes.

• Grip and clamp selection: use compatible soft-jaw grips that prevent damage to composite cores.

• Temperature corrections: calculate sag for expected operational temperatures, not just installation temperature.

Ningbo Changshi supplies sheave sets, specialized grips, and tensioning recommendations tailored to HTLS and composite conductors. We offer pre-project consulting to help teams select the right tools and tension parameters to protect conductor integrity and ensure long-term performance.
