The invention relates to a combined square stackable high-temperature superconducting degaussing cable structure which has a high current density and can bear a large current, and belongs to the fieldof a high-temperature superconducting degaussing cable. The high-temperature superconducting degaussing cable respectively comprises a core body, an insulation layer, an isolation strip, a liquid nitrogen passage, a low-temperature dewar tube and an outer protective sleeve in the radial direction from inside to outside, wherein the core body is formed by stacking superconducting strips. Accordingto the invention, a stacked cable core body structure is adopted, so that the current density of a current-carrier conductor can be further improved; the high-current-density combined square stackable high-temperature superconducting degaussing cable structure has a smaller weight and volume, and is simplified in structure and easy to produce.
