摘要：By means of scanning electron microscope, energy spectrometer and X-ray diffraction method, the chemical element analysis and phase analysis of the cross section, corrosion products, fire resistance mud and shielding line of the copper clad aluminum cable under the special service environment in the terminal box of the substation were analyzed and the corrosion mechanism was studied. Salt Mist corrosion test was carried out on the shielding line with dilute HCl solution, NaCl solution and NaOH solution. The results showed that there are Cl elements and AlCl3, CuCl and other substances in the corrosive products, and a large number of Cl elements are found in the corrosion resistance mud and shielding line outsourcing materials. The salt mist test showed that the dilute HCl solution makes the corrosion rate of copper clad aluminum wire the fastest, and the cause of corrosion fracture of copper clad aluminum wire is the result of chemical corrosion of acidic atmosphere, corrosion of primary battery and corrosion of electrolytic pool.
