Technical Field

[0002] In superconducting armored cable conductors (CICC), stainless steel armor is the main load-bearing component. In order to meet the requirements of the operating conditions of the future fusion reactor superconducting magnet armor, the armor material needs to have a yield strength greater than 1300 MPa, a tensile strength greater than 1800 MPa, and a fracture elongation greater than 25% in the temperature range of 20 K-4.2 K. CICC conductors are composed of multi-stage twisted cables and stainless steel armor. They are not only used in nuclear fusion reactors, but also in large superconducting energy storage power stations, nuclear fusion reactors, large high-energy physics accelerator magnets, nuclear magnetic resonance spectrometer magnets, strong field magnets, cosmic dark matter detection magnets and other equipment.

[0003] When superconducting armored cable conductors (CICC) are interconnected, one end of the conductor needs to be interfaced, so the thick-walled armor of the conductor must be circumferentially cut. Due to the large number of conductor types, there are currently not many corresponding cutting mechanisms that can achieve equal-thickness circumferential cutting. Summary of the invention
