| Abstract: |
| Based on accelerated corrosion test environmental spectra in Ningbo region, accelerated corrosion test was carried out on aluminum monofilament transmission wires. Corrosion weight loss and corrosion depth was analyzed with statistical method and the corrosion dynamic law of aluminum transmission line in Ningbo region was obtained. The results showed that weight loss based annual corrosion rate achieves maximum in the first three years; depth based annual corrosion rate achieves maximum in the first five years. It was concluded that corrosion development of aluminum wire is mainly in depth direction after three years. |
