Disclosed are an insulated pipe and an insulated bushing. The insulated bushing (1000) includes: an insulator (110) including an intermediate shed member (112), and a lower flange (114) arranged on a lower end of the shed member; a head member (120) connected to an upper end of the insulator, wherein the head member includes an oil conservator (121) connected to the upper end of the insulator and a connecting terminal (122) connected to the oil conservator; and an insulated pipe (100) connected to the lower flange, wherein the insulated pipe includes a upper transformer pipe (101) and a lower oil-immersed pipe (102), and the transformer pipe includes an inner pipe (103), and a conductive layer arranged outside the inner pipe and configured to be grounded. The insulated pipe and the insulated bushing solve the problems of connection and sealing, and save material cost greatly.
