Key Features & Benefits
Superior Cable Protection: Safeguards valuable and sensitive cables during high-tension pulls, preventing crushing, abrasion, and deformation.
Minimized Friction: Large-diameter sheave and sealed bearings reduce friction for efficient, controlled stringing operations with less force required.
High-Capacity Performance: Built to handle large-diameter conductors, bundled configurations, and extreme tensions for EHV transmission lines.
Maximum Durability: Corrosion-resistant aluminum alloys and sealed bearings withstand harsh field conditions for long-term reliability.
Enhanced Worksite Safety: Prevents cable snags and derailments, creating a safer working environment during critical pulling phases.
OPGW & Fiber Optic Compatibility: Specifically designed to protect delicate optical fibers with specialized sheave materials.
Improved Project Economics: Reduces friction for faster pulling speeds, less fuel consumption, and lower labor costs.
Professional Standard: Essential equipment for utility and transmission contractors committed to quality workmanship.
Grid Reliability Support: Contributes to building resilient infrastructure capable of handling peak loads and severe weather.
Foundational Investment: Capital investment in operational capability that protects multi-million-dollar cable assets.
The 660 Stringing Block is a precision-engineered solution for critical power line construction. It combines robust durability with friction-reducing performance to protect valuable assets, enhance jobsite safety, and drive operational efficiency. This indispensable tool ensures high-voltage network projects are completed to the highest standards of quality and longevity.
