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.
