Grounding Wire Stringing Block | Nylon Sheave Earth Wire Pulley for Transmission Line Construction

Product Introduction

The Grounding Wire Stringing Block is a specialized stringing tool designed for overhead transmission line construction, grounding wire installation, and earth wire pulling operations.

This product features a single sheave structure, hook-type mounting design, and steel support frame, providing reliable guidance and support during grounding wire installation.

The grounding wire pulley is mainly used to guide earth wires and grounding conductors during stringing operations. The nylon or composite sheave provides a smooth contact surface, helping reduce friction between the wire and pulley during movement.

With a compact structure and practical installation design, this Ground Wire Stringing Block is widely applied in power transmission projects, overhead line construction, and electrical infrastructure installation.

Product Features

Single Sheave Structure for Ground Wire Guidance

The single sheave design provides an efficient solution for grounding wire routing and installation.

It helps guide the wire during:

• Overhead transmission line construction
• Ground wire pulling operations
• Electrical line installation
• Power infrastructure projects

The compact structure allows convenient installation in different working environments.

Nylon / Composite Sheave Design

The pulley uses a nylon or composite material sheave, creating a smoother contact surface compared with direct metal contact.

The sheave structure helps:

• Reduce friction during wire movement
• Protect the surface of grounding wire
• Improve wire guiding performance

Hook Type Mounting Structure

The upper hook design allows flexible installation on transmission line structures.

The hook-type configuration provides:

• Easy attachment during field operation
• Convenient installation and removal
• Adaptability for overhead line construction environments

Steel Support Frame

The steel frame provides mechanical support for the sheave assembly.

The structure is designed for:

• Stable operation
• Outdoor construction applications
• Long-term field use conditions

Product Specification

Note: Dimensions, rated load capacity, and detailed technical specifications can be customized according to project requirements.
