Practical Guide to Preventing Electric Shock

How to select appropriate insulation products! Why does electrolysis occur? An explanation of everything about "electrical insulation."

Before taking measures against electrolysis, let's confirm the identity of the enemy once again. Electrolysis is a phenomenon where metals corrode due to electrical actions, and there are mainly two types. First, galvanic corrosion, which is a representative of electrolysis. When dissimilar metals (e.g., carbon steel bolts on stainless steel flanges) come into contact through an electrolyte such as water or condensation, a tiny battery (galvanic cell) is formed. Next is stray current corrosion. This occurs when current (stray current) leaking from railway tracks (using direct current) or other electrical equipment flows into nearby underground metal pipes through the ground and causes severe corrosion at the exit point when it flows back out into the earth. *For detailed content of the column, please refer to the PDF.
