Zusammenfassung:The HT-7U tokamak is a Chinese National Project. The mission of the project is to build an advanced full superconducting tokamak. NbTi strands are selected as the superconducting material. The copper ratio of the strands is 3.5 times less than that required by optimization; therefore, increasing the copper fraction in the cable is a key issue for conductor stability. Several versions of CICC with different configurations and surface treatment have been investigated and experimented with. Using segregated copper is a cost-saving option available to the HT-7U project.
