摘要： A gas turbine rotor cover (10) is described, comprising a body (20), the body comprising an inner side (22) facing towards a central axis (50) and an outer side (24) facing away from the central axis, wherein the gas turbine rotor cover is configured and arranged to extend in an axial direction (52) and a circumferential direction (54) relative to the central axis. An inner layer of insulation (30) is attached to the inner side of the body and extends along at least part of the length of the body in the axial direction and/or an outer layer of insulation (40) is attached to the outer side of the body, and extends along at least part of the length of the body in the axial direction. A gas turbine (60) containing the gas turbine rotor cover (10) is also described.
