Professional Answer: Proper tension and bending radius management are the most critical factors in ensuring a successful HV cable pull. At Ningbo Changshi, we advise our customers to follow these best practices:

• Pre-Pull Calculation: Always calculate the anticipated pulling tension using software or industry standards before starting the job. This helps select the correct equipment and plan the pulling route.

• Use High-Quality Lubricant: The use of an HV-rated, professional-grade cable lubricant is essential to reduce friction and minimize pulling tension.

• Utilize Correct Sheaves: Position large-radius sheaves at all bends to support the cable and maintain its minimum bending radius throughout the pull.

• Monitor in Real-Time: Use our tension and speed recorder to monitor and log the pulling parameters throughout the installation, providing a detailed record of the pull and ensuring the cable was installed within its specifications.
