Aluminum/Nylon Sheave 20KN Conductor Stringing Block for Three Direction Transmission Stringing

Aluminum/Nylon Sheave 20KN Transmission Stringing Block Three Direction Conductor Pulling

Product Overview

The Crossarm Mounted Three Purpose Stringing Block is designed for stringing wire on beeline and angle poles in three directions: straight, right and left. Suitable for single stranded aluminum and ACSR conductors on tangent structures. All sheaves mounted on ball bearings. Frame made of galvanized steel. Rated load 20KN, applicable conductor ≤LGJ240.

Technical Specifications

Applications

· Stringing wire on beeline poles (straight direction)

· Stringing wire on angle poles (right and left directions)

· Single stranded aluminum and ACSR conductor installation on tangent structures

· Overhead transmission line construction requiring multi-direction pulling

· Distribution line stringing projects

Product Advantages

· Three Direction Stringing — Enables straight, right, and left direction stringing from a single block, eliminating need for multiple specialized blocks.

· Lightweight Design — Only 4-4.3KG, easy to handle and install on crossarms at height.

· Ball Bearing Sheave — Silent, smooth rotation with minimal friction for consistent cable travel.

· Galvanized Steel Frame — Corrosion-resistant construction ensures long service life in outdoor environments.

· Dual Material Options — Aluminum sheave for heavy-duty use; nylon sheave for sensitive conductor protection.

· ISO 9001 Quality — Manufactured under strict quality control standards for reliable field performance.
