Oxygen-free copper rectangular magnet wire is a critical component used in the manufacture of power transformers, large electrical motors and other electrical equipment.Libo’s rectangular wire starts with our oxygen-free copper bar and, by using our continuous conforming technology with one-time molding process, we produce wire with a very high copper content (≥99.96%),compact structure, low resistivity, smooth surface, and flexible length.
Our wire comes in three categories TBR (soft), TBY1 (semi-hard), and TBY2(hard).We can also produce oxygen-free rectangular magnet wire to customers’ specifications and lengths as per their individual requirements.
