The present invention discloses a middle temperature electric tracing band for a self-limiting temperature oil well. The middle temperature electric tracing band comprise band core which is formed by two groups of conductive units in parallel arrangement. Each group of conductive units comprises two parallel tin-plated round wires, a conductive plastic layer arranged between the two tin-plated round wires, a fluorine plastic insulated inner layer coats the conductive plastic layer, and a shielding layer which coats the fluorine plastic insulated inner layer and is formed by weaving tinned soft round copper wires. The band core is coated by a polyolefin insulated outer layer which is coated by a fluorine plastic insulated outer layer, and the fluorine plastic insulated outer layer is coated by a reinforcing jacket and is made of fluorine plastic. The middle temperature electric tracing band has good wear resistance, and toughness and rigidity balance can be effectively considered.
