Corrosion Of Protective Layer
- Sep 19, 2018 -

electrochemical corrosion of underground stray current or chemical corrosion of non-neutral soil makes the protective layer lose its protective effect on insulation. The solution is to install the discharge device in the area with high stray current density. When the local soil in the cable line contains chemicals that damage the cable lead, the cable should be installed inside the pipe, and the cable should be padded and covered with neutral soil, and the cable should be coated with asphalt.
