Galvanized Steel Wire for ACSR (also known as Galvanized Steel Core Wire for ACSR or GSW for ACSR) is a high-tensile, heavily galvanized steel wire specifically engineered as the core reinforcement for Aluminum Conductor Steel Reinforced (ACSR) overhead conductors and grounding wires.
Produced from premium raw materials through advanced multi-stage drawing, annealing, and hot-dip galvanizing processes, it delivers exceptional mechanical strength, uniform heavy zinc coating, and outstanding corrosion resistance — essential for long-span, high-reliability transmission lines in diverse and harsh environments.
Key Applications
Galvanized Steel Wire for ACSR is widely used in:
- Core reinforcement in ACSR conductors for high-voltage and extra-high-voltage overhead transmission lines
- Grounding conductors and earth wires in power utility networks
- Messenger wires and supporting strands in telecommunication and power infrastructure
Its robust construction ensures the conductor maintains structural integrity under heavy wind, ice, and dynamic loads while providing long-term protection against atmospheric corrosion. This product is particularly suitable for cable manufacturers supporting large-scale grid projects in the Saudi Kingdom and GCC region under Vision 2030.
Outstanding Advantages
- Wide Diameter Range — 0.57 mm to 4.80 mm, perfectly matched to various ACSR core requirements.
- High and Stable Mechanical Performance — Narrow tensile strength tolerance ensures consistent quality during stranding.
- Heavy & Uniform Zinc Coating — Superior long-term corrosion resistance in coastal, industrial, and polluted environments.
- Excellent Processability — Smooth pay-off characteristics optimized for high-speed stranding machines.
- Premium Raw Materials & Full Process Control — Strict monitoring from steel rod to finished wire for reliable performance.
- International Standard Compliance — Meets the stringent requirements of global conductor manufacturers.
Manufacturing Standards
Fully compliant with major international specifications:
- ASTM B498 (Zinc-Coated Steel Core Wire for ACSR)
- BS 1052
- AS 3607
