Single Sheave Stringing Block | Nylon Sheave Conductor Pulley for Overhead Transmission Line Construction

Product Introduction

The Single Sheave Stringing Block is a professional conductor stringing tool designed for overhead transmission line construction, conductor pulling, and installation operations.

Featuring a single nylon sheave with a galvanized steel support frame, this conductor stringing pulley provides smooth conductor guidance and stable mechanical support during stringing operations.

The Single Sheave Stringing Block is commonly installed on transmission line structures and used together with tension stringing equipment to guide conductors during installation. The nylon sheave design helps reduce friction between the conductor and pulley surface, supporting conductor protection and controlled stringing processes.

With a compact structure and practical design, this single sheave conductor pulley is widely used in power transmission projects, overhead line construction, and electrical infrastructure applications.
