Single Sheave Stringing Block for Overhead Transmission Line Cable Stringing | Heavy Duty Cable Pulley with Shackle

Product Overview

The Single Sheave Stringing Block is a professional cable stringing pulley designed for overhead transmission and distribution line construction. It is widely used for guiding conductors, grounding wires, pilot ropes, and pulling ropes during cable installation projects.

Featuring a high-strength galvanized steel frame, precision-machined sheave, and heavy-duty shackle connection, this stringing block minimizes cable friction while ensuring smooth cable movement through the pulley groove. It helps reduce conductor wear, improve installation efficiency, and enhance safety during power line construction.

The sheave can be manufactured from MC nylon, aluminum alloy, or steel, allowing customers to choose the most suitable material according to conductor type, project requirements, and working conditions.

Suitable for transmission line contractors, utility companies, EPC contractors, and electrical infrastructure projects, this single sheave stringing block provides reliable performance for demanding field applications.
