Annealed copper stranded wire Conductor
Annealed Copper Stranded Wire, commonly abbreviated as WOAS (Wire, Overbraided, Annealed, Stranded), is a highly flexible electrical conductor widely used in power and control systems. Manufactured from soft-drawn copper strands, this wire combines excellent electrical conductivity with superior mechanical flexibility, making it ideal for both fixed installations and dynamic applications where repeated bending occurs.
Key Features
-
Stranded Copper Construction
Composed of multiple fine copper wires twisted together to form a single, flexible conductor. This structure enhances pliability and vibration resistance, offering significant advantages over solid conductors in terms of handling and fatigue life. -
Annealed for Flexibility
The copper undergoes an annealing process, a heat treatment that softens the metal. This makes the wire ductile and easy to bend without the risk of fracture—perfect for tight routing or moving parts. -
Excellent Electrical Conductivity
Made from high-purity copper, WOAS wire ensures low resistance and reliable current transmission across a wide range of voltages and frequencies.
Applications
-
Internal wiring for lighting fixtures, electrical panels, and power distribution systems
-
Flexible connections in control panels, machinery, switchgear, and appliances
-
Automotive and marine wiring where movement and vibration are constant
-
Power leads in robotics, industrial automation, and renewable energy systems
Advantages
-
Superior Flexibility: Ideal for dynamic environments or confined spaces
-
Easy to Route & Install: Saves time during installation, especially in complex layouts
-
Long-Term Durability: Resists breakage due to mechanical stress or vibration
-
Multi-Standard Compliance: Reliable across global markets
