Product Description

660mm Triple-Sheave Nylon Stringing Block for Pilot Wire Rope

Professional overhead line stringing tool designed for transmission line construction applications.

Product Overview

The 660mm 3-Sheave Nylon Stringing Block is engineered specifically for pilot wire rope guiding during overhead transmission line construction. Featuring a three-sheave design with high-strength nylon wheels, this tool ensures smooth rope running, reduced friction, and superior protection during conductor or pilot rope stringing operations. Ideal for 110kV-500kV line projects, this block is widely used for rope traction from tower to tower before pulling conductors.

Product Definition

A Stringing Block is a wheel-type guiding tool used for pulling pilot wire rope or conductors along power transmission lines. This model features 660mm outer diameter nylon sheaves with a three-groove design for stable rope guiding, suitable for steel pilot rope, PP rope, and synthetic pulling rope applications.

Key Features

Triple-Sheave Design: Three grooves ensure stable rope guiding without jumping or twisting
High-Density Nylon Sheaves: Low friction, wear-resistant construction that's gentle on rope surfaces
Reinforced Aluminum Alloy Frame: Lightweight yet high-strength structure for safety in heavy-duty field use
Smooth, Low-Resistance Bearings: Improves pulling efficiency and reduces load on tensioners and pullers
Wide Rope Compatibility: Ideal for steel pilot wire rope, PP rope, composite rope, and traction lines

Product Advantages

Reduced wear on pilot rope with nylon grooves that prevent friction burn and minimize rope deformation
High working load capacity suitable for mountain or long-span line applications
Lightweight design for easy tower mounting and quick installation
Versatile application for both pilot rope guiding and small conductor pulling
Customizable options including groove diameter, frame type, hook connection, and grounding roller

Applications

Pilot rope stringing for 110kV / 220kV / 330kV / 500kV transmission lines
Tower-to-tower rope pulling operations
Conductor and OPGW preliminary guiding
Long-distance and mountain terrain line construction
Use with hydraulic pullers and tensioners

Frequently Asked Questions

Q1: Can the sheave material be changed to aluminum?

Yes. We provide aluminum sheaves, MC nylon, or rubber-lined grooves upon request.

Q2: What rope diameter is compatible?

We can customize the groove to match 8-18mm pilot rope or your project specifications.

Q3: Can the working load be upgraded?

Yes, working load can be adjusted from 20kN to 60kN depending on frame design.

Q4: Do you supply matching pullers and tensioners?

Yes. We can supply full sets of stringing equipment for turnkey projects.

Q5: What is the typical lifespan?

Normal working conditions allow 8-12 years of service life.
