Product Description
Alloy Steel Stringing Swivel Joint Anti Twist Rotating Connector for ACSR AAC Overhead Transmission Conductors
Product Overview
The Stringing Swivel Joint is a critical component in overhead transmission line conductor stringing operations, engineered to prevent conductor twisting, torsion, and birdcaging during tension pulling. Constructed from premium 40Cr alloy steel with a heavy-duty sealed thrust ball bearing mechanism, this rotating connector ensures smooth 360-degree rotation under full working load, maintaining conductor integrity throughout the stringing process.
Key Features
- Heavy-Duty Ball Bearing Mechanism: Sealed thrust ball bearing design enables smooth, effortless 360-degree rotation even under maximum working load, effectively releasing built-up torsional stress in the conductor.
- Premium Alloy Steel Construction: Forged from 40Cr/35CrMo alloy steel with precise heat treatment, delivering exceptional tensile strength and fatigue resistance for demanding field conditions.
- Anti-Twist Performance: Automatically neutralizes rotational forces generated during tension stringing, preventing conductor birdcaging, kinking, and strand damage.
- Multiple Connection Options: Available with clevis pin, eye type, or screw pin end connections to mate with pulling grips, running boards, and conductor hardware.
- Safety Factor 3:1: Each unit rated with minimum breaking load of 3 times the working load limit, exceeding industry safety standards for overhead line construction.
- Corrosion Resistant: Hot dip galvanized surface treatment ensures long service life in outdoor, high-humidity, and coastal environments.
