Bi-2223 Current Leads
|
Superconducting tubes of BiPbSrCaCuO (Bi-2223 phase) ceramics with silver covered ends of a low contact resistance are suitable for current leads effectively reducing heat leak into superconducting magnets. The leads may also be used as resistive current limiters. Upon request the leads can be encased into a protective tube.
