Superconducting cable welding-free sealing end and installation method

The invention discloses a superconducting cable welding-free sealing end and an installation method, and relates to the technical field of cables. The sealing end comprises an outer pipe fastening sleeve, an inner pipe fastening sleeve is arranged in the outer pipe fastening sleeve, and a second pipe fitting and a first pipe fitting which are used for being connected with the outer corrugated pipe and the inner corrugated pipe in a sealed mode are arranged in the outer pipe fastening sleeve and the inner pipe fastening sleeve respectively. A crimping end used for integrally connecting the supporting body and the cable core body is arranged in the inner pipe fastening sleeve, and one side of the crimping end is connected with a traction end used for pulling the superconducting cable. Through mutual cooperation of the outer pipe fastening sleeve, the inner pipe fastening sleeve, the second pipe fitting of the outer corrugated pipe used for sealing connection, the first pipe fitting used for connecting the inner
