Why Hard Drawn vs Soft Drawn?

When metal is cold worked or formed it becomes work hardened or strain hardened. Copper conductors go through a considerable amount of work hardening as the copper rod is drawn down through ever decreasing die sizes until the required conductor dimension is achieved. Copper in this state is known as hard drawn copper. Hard drawn copper has significantly higher tensile strength than soft annealed copper and is used as overhead wire whereas the soft annealed copper is flexible and has somewhat improved conductivity over hard drawn copper conductor.  

 

Annealed copper – Tensile strength 300-400 ksi (kilopound per square inch). 

 

Hard drawn copper – 500-700 ksi. Conductivity 97 % IACS

 

Hard drawn has better anti corrosive properties, is mechanically stronger and does not bird cage. Hard drawn is also mainly always specified when being used on any DNO side of a project.

Benefits
  • No Bird Caging
  • Less Corrosive
  • Higher Mechanical strength compared to Soft Drawn
