Hold Down Wire Block: Heavy-Duty Anti-Lifting Conductor Stringing Block (10-40KN)

The SHY series Hold Down Wire Block is a specialized power transmission tool designed to manage upward tension during conductor stringing operations. By applying downward pressure on earth wires or conductors, this block prevents lifting and ensures the cable follows the designated path.

Engineered with a spring-loaded automatic release system, it allows for seamless cable detachment, significantly enhancing safety and efficiency in overhead line construction.

To ensure consistency in high-tension environments, each block is manufactured with calibrated load capacities:

• Automatic Release System: Features an integrated spring-release mechanism that enables the pulley to detach from the cable automatically once the task is complete.
• High-Strength Construction: The frame is built from high-quality galvanized steel, providing superior corrosion resistance and structural integrity under loads up to 40KN.
• Precision Rotation: All sheaves are mounted on high-performance ball bearings to minimize friction and ensure smooth conductor passage.
• Customizable Sheave Materials: Available in MC Nylon, Steel, or Aluminum (with optional rubber liners) to suit specific conductor types and prevent surface damage.

• Overhead Transmission Lines: Critical for stringing conductors and ground wires where upward forces occur.
• Utility Infrastructure: Used in the deployment of ACSR cables up to LGJ720 standards.
• Conductor Tensioning: Stabilizes the pulling path during complex terrain stringing.
