Product Description

822mm Large-Diameter Cable Pulley Block

Heavy-duty stringing block designed for guiding and supporting conductors during overhead transmission line construction operations.

Product Overview

The 822mm Large-Diameter Cable Pulley Block is engineered for guiding and supporting conductors during overhead transmission line stringing operations. With its extra-large 822mm sheave diameter and reinforced frame, it ensures smooth conductor passage, reduced friction, and excellent mechanical stability for medium- and high-voltage power line projects. Ideal for long-span, mountain, and high-load stringing applications.

Product Definition

A cable pulley block is a specialized guiding device used during conductor installation. This heavy-duty model features:

Large 822mm sheave for reduced bending stress
Heavy-duty frame construction for maximum durability
Compatibility with various conductor types including ACSR, AAAC, ACCC, and OPGW

Designed for use with pulling machines, tensioners, and pilot rope systems.

Key Features

Extra-Large 822mm Sheave: Provides wide guiding radius to protect conductor surface and improve pulling efficiency
Heavy-Duty Frame Structure: Built for strength and stability in demanding overhead line environments
Smooth Low-Friction Bearings: Ensures consistent rotation, reduces pulling resistance, and supports long-distance stringing work
Versatile Conductor Compatibility: Suitable for single or bundled conductors depending on groove customization
Optional Custom Configurations: Available options include groove material, hook styles, grounding rollers, and special coatings

Product Advantages

Reduced Stress on Conductors: Larger diameter minimizes conductor bending and surface abrasion
Built for Harsh Field Conditions: Ideal for mountain terrain, long-span towers, and high-tension applications
Long Service Life: Durable materials and sealed bearings provide extended operational use
Compatible With All Major Stringing Equipment: Works with hydraulic tensioners, pullers, pilot ropes, swivels, and overhead line accessories
Safe and Efficient Stringing: Stable frame geometry ensures reliable conductor guidance under heavy loads

Applications

Conductor installation for 110kV, 220kV, 330kV, 500kV transmission lines
Single or bundled conductor stringing operations
OPGW and ADSS cable guiding
Long-span and mountain line construction
Tower-to-tower pulling operations
Use with pullers, tensioners, and pilot rope systems
