The invention discloses a method for predicting the corrosion life of transmission line hardware in an industrial area. The method for predicting the corrosion life of the transmission line hardware in the industrial area comprises the following steps: (1) sampling from the hardware from the transmission line; (2) connecting a copper wire and packaging epoxy resin; (3) calculating the local annual average potential hydrogen (pH) value of acid rain; (4) configuring simulated acid rain solution; (5) putting the simulated acid rain solution into a three-electrode system electrolytic tank to test; (9) calculating annual average rate of the corrosion depth in a medium-long term; (10) measuring the average value of the thickness of the zinc coating of the hardware; and (11) obtaining the rest of corrosion life of the zinc coating. The method for predicting corrosion life of the transmission line hardware in the industrial area has the advantages that the traditional constraints is broken, the thickness of the zinc coating which is arranged on the surface can be measured, evaluations of the corrosion speed and the service life of the transmission line hardware in the industrial area wherein the pH value of the acid rain is <=5.2 can be achieved, the evaluation is fast and accurate, and the safe of power grids is guaranteed.
