Description
20kN OPGW Cable Pulley Block Max 22mm Fiber Optic Cable Tools Stringing Blocks for Transmission Line Installation
Product Overview

The 20kN OPGW cable pulley block is engineered for fiber optic cable stringing, OPGW installation, cable pulling, and transmission line construction. Designed for OPGW cable with a maximum diameter of 22mm, it ensures stable cable guidance during overhead power line installation.

As an essential fiber optic cable tool, this pulley block minimizes cable friction, protects the OPGW surface, and enhances cable stringing efficiency in power line construction projects.

Key Features
  • 20kN Rated Load: Suitable for OPGW stringing and fiber optic cable pulling in transmission line projects
  • Max 22mm Cable Diameter: Designed for OPGW and fiber optic cable installation up to 22mm diameter
  • Cable Protection Design: Reduces cable surface wear and pulling friction during stringing operations
  • Lightweight and Practical Structure: Easy to transport and ideal for outdoor transmission line construction sites
  • Customizable Design: Pulley material, hook type, frame structure, and size can be tailored to project requirements
Problem Solving

Common Challenges: Cable surface damage during pulling, high friction during long-distance stringing, unstable cable guidance, low efficiency with unsuitable tools, difficulty selecting correct pulley blocks.

Our Solution: The 20kN OPGW cable pulley block addresses these issues with its 20kN rated load capacity, 22mm maximum cable diameter compatibility, smooth pulley groove design, and customizable features for various transmission line project requirements.

How It Works

The OPGW cable pulley block guides fiber optic cable through its rotating pulley during cable pulling and stringing operations. The pulley supports the cable and reduces direct friction between the cable and construction structures.

During transmission line installation, the OPGW cable passes smoothly through the pulley groove, protecting the cable surface and maintaining stable pulling direction. This improves installation efficiency and reduces cable damage risk.

Applications

This 20kN OPGW cable pulley block is widely used in:

  • OPGW cable stringing
  • Fiber optic cable installation
  • Transmission line construction
  • Power line installation
  • Overhead line stringing
  • Cable pulling projects
  • Utility construction projects
Selection Guide
  • Choose 20kN Rated Load If: Your project requires a medium-duty pulley block for OPGW or fiber optic cable installation
  • Choose Max 22mm Cable Diameter If: Your OPGW cable diameter is 22mm or smaller
  • Choose OPGW Cable Pulley Block If: You need to protect fiber optic cable during overhead stringing work
  • Choose Customized Version If: Your project requires specific pulley groove, hook type, frame design, or pulley material
