The invention provides a conductive tube for high-voltage equipment. The conductive tube comprises a main tube body, an end portion insertion tube, and a disc-shaped plugging block; the main tube bodyand the end portion insertion tube are respectively in insertion connection with two ends of the disc-shaped plugging block; the end portions of the main tube body and the end portion insertion tubeare fixedly connected with the disc-shaped plugging block; one end, far away from the disc-shaped plugging block, of the end portion insertion tube is an insertion end which is in insertion connectionwith a contact seat on an insulating support; two ends of the disc-shaped plugging block can support the main tube body and the end portion insertion tube correspondingly, and therefore, when the endportions of the main tube body and the end portion insertion tube are fixed to the disc-shaped plugging block; and high connection strength is achieved between the disc-shaped plugging block and themain tube body and between the disc-shaped plugging block and the end portion insertion tube; structural deformation at a fixed position can be avoided; and it is guaranteed that the conductive tube has good power transmission performance when being used.
