GSW-Galvanized Steel Wire Bare Conductor IEC 61089 For Power Transmission System

APPLICATION

• ACSR Conductors‌:Used as the core of ‌Aluminum Conductor Steel Reinforced (ACSR)‌ cables, providing structural strength and conductivity‌
• Messenger Wires‌: Deployed in overhead communication lines for supporting optical fibers or electrical cables‌
• Guy Wires & Stay Wires‌:Provides tension support for telecommunication towers, power poles, and wind turbines‌
• Ground Wires & Barrier Cables‌: Acts as a protective shield in power transmission systems against lightning strikes‌
  
  

CONSUTRUCTION 

The galvanized steel wire strand is manufactured by concentrically stranding single wires helically around a central core.

 Available in three galvanizing classes:

• ‌Class A‌: Standard zinc coating (minimum thickness)
• ‌Class B‌: Intermediate zinc coating
• ‌Class C‌: Heavy zinc coating (maximum thickness)

The coating weight increases progressively from Class A to Class C, with Class C offering superior corrosion resistance.

FAQ

Q: How does the galvanizing process protect GSW?‌
A: The ‌hot-dip galvanized coating‌ prevents rust and extends the cable’s lifespan, especially in harsh environments like coastal or industrial areas.

Q: What tensile strength can GSW cables withstand?‌
A: Typical tensile strength ranges from ‌1,500 to 4,000 MPa‌, depending on diameter and strand configuration (e.g., 7/1.57mm).

Q:Can GSW cables be used in underground installations?‌
A: While GSW is designed for overhead applications, it can be used underground if ‌properly insulated‌ to prevent moisture ingress.

Q: What are the standard diameters for GSW strands?‌
A: Common diameters include ‌3/3.05mm, 1/4'', and 3/16''‌, with customizable lay types (left/right).

Q: How does GSW compare to aluminum conductors?‌
GSW offers ‌higher strength-to-weight ratio‌ and is often used as a reinforcing core in hybrid ACSR cables.

Q: What maintenance does GSW require?‌
A: Minimal maintenance is needed due to galvanizing, but periodic inspections for ‌coating integrity‌ are recommended.
