Copper as conductor for cables is used as________?
Correct answer: A. annealed
- A. annealed
- B. hardened and tempered
- C. hard drawn
- D. alloy with chromium
Explanation
Cable conductors are generally made from annealed copper because heat treatment makes copper soft, flexible and easy to draw into strands. Hard-drawn copper is stronger but less suitable where cable flexibility is needed.
