UHVDC transmission line porcelain and glass insulator iron caps are seriously corroded, safe and effective anti-corrosion measures are of great significance for the stable operation of the power system. In order to determine the key parameters of PRTV spraying on the surface of insulator iron cap, a three-dimensional finite element model of insulator is established, and the test verified the feasibility of PRTV anti-corrosion of iron cap. The research results show that PRTV can effectively reduce the leakage current density of the insulator iron cap. PRTV can effectively prevent corrosion of the insulator iron cap, and can reduce the surface fouling speed of the insulator, improve the surface resistance of the insulator, and inhibit the insulator flash. The research results can provide reference for the research of anti-corrosion of insulator iron cap.
