Hard-drawn Copper Stranded Wire for Electrical Purpose (WOHS) APPLICATION
Hard-drawn copper stranded wire is a robust electrical conductor prized for its exceptional high tensile strength and durability. It's the go-to choice for applications where mechanical resilience is paramount, such as overhead power transmission lines and earthing grids, all while maintaining excellent electrical conductivity. This type of wire is preferred over softer, annealed copper when strength is a critical factor in performance.
Key Characteristics
- High Tensile Strength: The drawing process involved in creating hard-drawn copper work-hardens the metal, making it mechanically stronger than soft annealed copper.
- Good Conductivity: While not as conductive as its soft annealed counterpart, hard-drawn copper still provides excellent electrical conductivity for most electrical applications.
- Corrosion Resistance: Copper naturally resists corrosion, making this wire suitable for diverse environments, including those with exposure to moisture or salinity.
- Flexibility: The stranded construction of hard-drawn copper offers greater flexibility compared to solid hard-drawn copper, allowing for more intricate and complex installations.
- Durability: The potent combination of high strength and good conductivity makes hard-drawn copper stranded wire a remarkably durable option for long-term electrical use.
Common Applications
Hard-drawn copper stranded wire is a versatile solution, frequently deployed in critical electrical infrastructure:
- Overhead Transmission and Distribution Lines: Its strength and conductivity make it an ideal material for overhead power lines, ensuring reliable energy transfer.
- Earthing Grids: It's well-suited for buried earthing grids, particularly in large-scale projects like solar and wind farms, providing essential grounding.
- Other Electrical Installations: This wire can be utilized in a wide array of other electrical applications where a strong, reliable, and high-performing conductor is required.
Standards
