Aluminum Clad Steel Strand Wire (ACS), also known as Aluminum-Clad Steel Conductor أو ACS Strand, is a high-performance bimetallic stranded wire consisting of a high-strength steel core metallurgically bonded with a thick, uniform layer of aluminum. This unique construction combines the superior tensile strength and fatigue resistance of steel with the excellent conductivity and corrosion resistance of aluminum, making it the ideal reinforcement material for long-span overhead transmission lines, optical fiber composite overhead ground wires (OPGW), and extra-high-voltage conductors.
Key Applications
Aluminum Clad Steel Strand Wire is widely used in:
- Long-span transmission lines and river crossings
- Overhead ground conductors (OGW) and static wires
- Extra-high-voltage (EHV) overhead conductors
- Optical fiber composite overhead ground lines (OPGW)
- Self-damping conductors and grounding systems
Its outstanding mechanical and electrical properties make it especially suitable for coastal, high-pollution, and heavy-loading environments where conventional galvanized steel strands may corrode rapidly.
Outstanding Advantages
- Combines high tensile strength of steel with the conductivity and corrosion resistance of aluminum
- Excellent long-term corrosion protection due to the metallurgical bond between aluminum and steel
- Superior fatigue resistance and low sag performance for long-span applications
- High conductivity reduces I²R losses in grounding and OPGW applications
- Stable performance with tight tolerance control on breaking strength and diameter
