Manufacture of Cu-Zn Composite Delaying Time Fuse Wire

In this paper,the technique of preparting delaying time fuse composite wire by sleeve drawing is studied in detail. Delaying time property of Cu-Zn and Cu-Zn-0.5wt%Al composite wire has come up to the IEC standard. Specifically, Cu-Zn-0.5wt%Al composite wire is satisfactory to JIS standard and for delaying time fuses.
