Product Description
660 mm Bundled Conductor Pulley Block with Nylon Wheel
Heavy-duty stringing pulley designed for overhead transmission line construction with large 660 mm diameter sheave for smooth conductor passage.
Product Overview
The 660 mm Bundled Conductor Pulley Stringing Block with Nylon Wheel is a high-performance pulley block engineered for overhead transmission line construction. Its large 660 mm diameter sheave ensures smooth passage of bundled conductors while minimizing friction and preventing conductor surface damage. The nylon wheel provides low friction operation and extended service life, making it ideal for medium- to high-voltage conductor stringing projects.
Product Definition
A stringing pulley block is a mechanical device used to guide and support conductors during installation. This model features a 660 mm large-diameter sheave, durable nylon wheel, compatibility with double or triple bundled conductors, and a high-strength steel or aluminum alloy frame for stability and long service life.
