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.

Key Features

Large 660 mm Diameter Sheave: Ensures smooth conductor passage, reducing friction and preventing conductor damage
Nylon Wheel/Sheave: Low-friction material protects conductors and extends pulley lifespan
Heavy-Duty Frame: Steel or aluminum alloy frame ensures stability, durability, and safe operation
Multi-Bundle Compatibility: Supports double and triple bundled conductors, optimizing stringing efficiency
Portable & Easy to Install: Lightweight design allows quick deployment on transmission towers and construction sites

Product Advantages

Protects conductor surface with smooth nylon sheave that minimizes scratches and bending stress
Reliable performance for high-voltage lines including 110 kV, 220 kV, 330 kV, and 500 kV transmission projects
Reduces labor and time with large-diameter sheave and low-friction nylon wheel
Long service life through durable frame and nylon wheel construction
Compatible with standard stringing tools including tensioners, pullers, and pilot rope systems

Applications

Bundled conductor stringing in overhead transmission lines
Medium- and high-voltage line construction
Tower-to-tower conductor guidance
Use with pilot ropes, pullers, and tensioners
Long-span and complex terrain conductor installation
