Mô tả sản phẩm

Double Sheave Stringing Block for Overhead Line Construction

Dual-pulley cable guide designed for transmission projects with precision-machined sheaves that reduce friction, improve cable alignment, and ensure smooth, safe stringing operations.

Product Overview

The Double Sheave Stringing Block is a durable, high-efficiency pulley tool engineered for guiding conductors, OPGW, ADSS, and communication cables during overhead transmission line construction. This dual-pulley block is widely used by power utility companies, EPC contractors, and line construction teams for 11kV-500kV transmission projects.

What Is a Double Sheave Stringing Block?

A cable-guiding pulley equipped with two sheaves to support and guide conductors during stringing or sagging work. The dual-sheave design offers improved load distribution, smoother running, and reduced conductor wear, making it ideal for multi-layer cable pulling or heavier loads.

Key Features

Dual Sheave Design: Two balanced sheaves for smoother cable entry and reduced tension, suitable for single or bundled conductors
High-Strength Materials: Aluminum alloy or nylon sheaves available - lightweight, corrosion-resistant aluminum and wear-resistant nylon for fiber optic cables
Robust Frame Construction: Heavy-duty steel frame with anti-rust coating and high structural strength for long-term outdoor operation
Smooth Ball-Bearing Operation: Precision bearings ensure low-friction rotation and enhance cable protection during stringing
Versatile Hook Options: Hook type, clevis type, or swivel type compatible with various field applications

Advantages

Excellent Cable Protection: Smooth sheave surfaces minimize abrasion and reduce conductor damage
High Load-Bearing Capacity: Engineered for high-tension transmission line pulling operations
Long Service Life: Corrosion-resistant materials ideal for harsh outdoor environments
Flexible Configuration: Available in different sheave diameters and groove types for ACSR, AAAC, OPGW, ADSS, etc.
Easy to Install & Operate: Lightweight structure for quick setup in the field

Applications

Overhead transmission line construction (11kV to 500kV)
Conductor stringing and sagging operations
OPGW/ADSS cable installation
Communication line projects
Mountain, valley, and long-span power line stringing
Electrical utility and EPC contractor field work

Frequently Asked Questions

What types of cables can this double sheave pulley handle?

It can handle ACSR, AAAC, OPGW, ADSS, communication cables, and bundled conductors.

Is the sheave material customizable?

Yes. Aluminum alloy is ideal for high-tension steel conductors; nylon is recommended for optical fiber cables.

What load capacity does it support?

Typical models range from 10 kN to 40 kN. Customized higher loads are also available.

Can the hook be changed?

Yes. Hook, clevis, and swivel types are all available.

Is it suitable for long-span or mountain transmission lines?

Absolutely. The dual-sheave structure ensures stable performance in challenging terrain.

Do you offer single, triple, and five-sheave blocks too?

Yes, complete conductor stringing block series can be provided.
