Sectional power temperature compensation heating rod

The utility model specifically relates to a sectional power temperature compensation heating rod which is applied to non-PVC flexible package infusion solution production lines. The sectional power temperature compensation heating rod comprises a heating rod housing and at least two sections of heater strip-wrapped matrix magnesium oxide rods. The magnesium oxide rods are located in the heating rod housing, a heater strip is wrapped around the periphery of each magnesium oxide rod, two copper rods which are independent from each other pass through the magnesium oxide rods, the two copper rods are pressed onto two outgoing lines respectively, the starting point of each heater strip and one copper rod of the two copper rods are welded together, the ending point of each heater strip and the other copper rod of the two copper rods are welded together, and magnesium oxide power is filled into the gap between the heating rod housing and the magnesium oxide rods. By adopting the sectional structure, the power on one
