Product Description

Heavy-Duty Aluminum Nylon Conductor Pulley Blocks

Professional stringing pulley blocks designed for double and triple bundled conductors (300-900mm²) with working load capacity of 40-105kN. Ideal for overhead transmission line construction projects.

Product Overview

Aluminum-Nylon Stringing Pulley Blocks are engineered for overhead transmission line construction, specifically designed for double and triple bundled conductors. With a working load range of 40-105kN, these pulley blocks ensure smooth conductor handling, reduced friction, and high reliability during stringing operations.

Widely used in 110kV-500kV line projects, they provide stable guiding and protection for conductors and OPGW during installation.

Product Definition

A Stringing Pulley Block is a wheel-based guiding device used during conductor installation to reduce friction and prevent conductor damage.

Aluminum alloy frame for superior strength
High-density nylon sheaves for minimal friction
Compatible with two- or three-bundled conductors

Key Features

Durable Aluminum Alloy Frame: Excellent strength-to-weight ratio, corrosion resistance, and long service life
Nylon Sheave with Smooth Rotation: Low friction coefficient prevents scratching or deformation of conductors
40-105kN Working Load: Suitable for medium and heavy-duty line stringing operations
Support for 2-3 Bundled Conductors: Stable guiding for double or triple conductor arrangements
High-Quality Bearings: Ensures smooth rotation and reduces pulling resistance
Optional Grounding Device / Lining Protection: Customizable based on project requirements

Product Advantages

High Strength & Lightweight: Aluminum alloy housing provides rigidity while reducing overall weight
Reduced Conductor Wear: Nylon groove protects the surface of conductors and OPGW
Lower Friction, Higher Efficiency: Professional bearing design reduces pulling force requirements
Broad Compatibility: Applicable for 300-900mm² conductors and 40-105kN hydraulic tensioners
Reliable Performance: Stable structure ensures consistent performance under continuous load

Applications

Overhead transmission line stringing (110kV-500kV)
ACSR / AAAC / ACCC conductor installation
Double or triple bundle conductor guiding
OPGW & ADSS fiber optic cable stringing
Tower-to-tower conductor pulling operations

Frequently Asked Questions

Q1: Can the pulley blocks be customized?

Yes, we offer custom sizes, groove types, grounding rollers, and connection fittings.

Q2: Are nylon wheels suitable for heavy conductors?

Yes. Engineering-grade nylon provides excellent wear resistance and minimizes conductor damage.

Q3: What conductor types are compatible?

ACSR, AAAC, ACCC, OPGW, and similar overhead conductors.

Q4: How long is the service life?

Typically 8-15 years, depending on usage frequency and environmental conditions.

Q5: Do you provide matching tools (tensioner, puller, rollers)?

Yes. We offer a full set of stringing equipment for turnkey solutions.
