Product Description

SHDN660 Steel-Frame Single Conductor Stringing Block

660mm Transmission Line Pulley for overhead transmission line construction

Product Overview

The SHDN660 Steel-Frame Single Conductor Stringing Block is engineered for guiding and supporting conductors during overhead transmission line construction. Featuring a durable steel frame and 660mm diameter sheave, this model ensures smooth conductor passage, reduced friction, and reliable performance for medium- and high-voltage line projects. Ideal for 110kV-500kV transmission line stringing operations.

Product Definition

A stringing block is a pulley-type guiding tool used to support and direct conductors during line installation. The SHDN660 model features:

Heavy-duty steel frame construction
Single-groove sheave for single conductor applications
High mechanical strength for demanding field conditions

Key Features

660mm Sheave Diameter: Provides large guiding radius to reduce conductor bending stress and protect surface integrity
High-Strength Steel Frame: Excellent load-bearing capacity and long-term durability in harsh environments
Low-Friction Smooth Bearings: Ensures efficient rotation, reduces pulling resistance, and improves stringing efficiency
Single Conductor Design: Compatible with ACSR, AAAC, ACCC, and similar conductor types
Customizable Options: Aluminum sheaves, nylon sheaves, grounding rollers, swivel hooks, and connection fittings

Performance Advantages

High structural strength for overhead line work with enhanced rigidity and stability
Protects conductor surface during installation with smooth sheave rotation
Compatible with various stringing equipment including hydraulic tensioners, pullers, and pilot rope systems
Reliable performance for long-span or mountain terrain projects under continuous load conditions
Long service life with minimal maintenance requirements

Applications

Overhead transmission line stringing (110kV-500kV)
Single-conductor installation for ACSR, AAAC, ACCC
Pilot rope to conductor stringing transition
Tower-to-tower pulling operations
Mountain and long-span construction projects
