What are the primary differences between wire stringing blocks with nylon sheaves and those with aluminum sheaves?

2025-08-08

The choice of sheave material is crucial for the safety and integrity of your wire or conductor.

  • Nylon Sheaves: High-strength MC nylon sheaves are prized for their non-conductive properties, making them an excellent safety choice, especially when working near live lines. They also offer a low-friction surface, which is gentle on the wire's surface, preventing damage and minimizing wear.

  • Aluminum Alloy Sheaves: Aluminum sheaves are a classic industry choice, offering a great combination of strength and lightweight design. Our aluminum sheaves can be lined with neoprene for extra protection, creating a cushioned surface that further reduces friction and prevents abrasion on the conductor during the stringing process.
