Disclosed are a stress-resistant, creep-resistant, high-temperature resistant and high-insulation sheath material for a maglev train cable, and a manufacturing method and use thereof. A multiple chemical crosslinking structure is constructed by blending a functional polyvinylsilicone grease with ultra-high molecular weight polyethylene (UHMWPE) and a ceramicized silicone rubber as a cable material matrix and using electron beam irradiation. In addition, organic/inorganic fillers in the matrix can form physical crosslinking points in the material. A physical-chemical dual crosslinking structure is constructed in the matrix, which can limit the motion and relaxation of molecular chains and improve the interaction between the insulation layer and sheath layer and refractory layers such as fillers and mica tapes to avoid the relative displacement during the laying and operation and improve the high-temperature resistance, creep resistance and stress relaxation resistance of a UHMWPE cable sheath material.
