| Abstract: | Based on 3-channel twisted stacked-tape cable conductor and quasi-iso tropic strand, this paper proposes 3-channel quasi-isotropic conductor. These kinds of conductors were modeled using self-consistent models in the finite element simulation software, and the relationships between the critical current, critical current anisotropy, engineering current density and conductor radius of the two 3-channel conductors were analyzed and compared. The simulation results show that the 3-channel quasi-isotropic conductor is useful under background field conditions, and it is also proposed to improve the engineering current density of these 3-channel conductors. |
