An electric heating tape of a gathering and transporting pipeline of an oilfield comprises a transformer (4), a rectifier (5), a triode (9), an electric contact thermometer (10) and the like. The electric heating tape is characterized in that one end of a power source (1) connected with an electric heating tape body (3) is serially connected with a normally closed contact (2) which is integrated with a relay (7). The electric heating tape has the advantages that the electric heating tape is used for preserving heat of the outdoor gathering and transporting pipeline of the oilfield, the working time of the electric heating tape can be reasonably controlled by an automatic control element, accordingly, electric energy can be saved, and the service life of the electric heating tape can be prolonged.
