Galvanized Steel Wire (GSW) Conductor is a stranded wire product formed by twisting together multiple zinc-coated steel wires. Designed primarily for mechanical support, GSW is widely used in overhead line applications due to its excellent tensile strength and corrosion resistance. It is an essential component in power transmission, telecommunications, and structural reinforcement.
This product complies with IEC 61089, which defines the technical requirements for round wire concentric lay overhead electrical stranded conductors.
Standard
ASTM A475, ASTM A363, IEC 61089 BS183:1972 and ect.Other International Standard.
Key Features
Corrosion Resistance
The zinc coating applied through the galvanization process enhances the steel's resistance to atmospheric corrosion, making it suitable for long-term outdoor use.High Mechanical Strength
GSW conductors offer excellent tensile strength and are capable of bearing significant mechanical loads, suitable for structural and load-bearing functions.Cost-Effective & Durable
The simplicity of production and durability of galvanized steel make it a reliable and economical choice for mass applications.Reliable Performance
Engineered for consistency and long service life in both standard and high-stress environments.
Application
GSW conductors are used across various utility and structural applications, including:
Earth Wire (Ground Wire) in overhead power lines
Stay Wire for supporting utility poles
Messenger Wire for telecom and fiber optic systems
Core Wire in ACSR conductors
Structural Reinforcement in fences and towers
Guy Wires for antenna or pole support systems
