2, it is checked and is found by down conductor surface to a large amount of base shaft towers and excavating, exceed the grounding lead of above ground portion
The offline down conductor part with after burying is not easy corrosion, and corrosion situation mostly occurs in ground surface layer and connect with down conductor
At the 20-30cm of synapsis, due to being in cultivation region, slant acidity in soil, perishable chemical composition is more, and moisture is high, changes
The serious round steel of Φ 12 can be corroded to Φ 6 of corrosion is learned to be broken hereinafter, down conductor even occurs.
