Mechanism of Corrosion in Porcelain Insulators and Its Effect on the Lifetime

Applied Sciences, 2020
Porcelain insulators should be exchanged periodically, but their lifetime is not clearly defined. One factor that affects service life is corrosion occurring at the pin and cap—each of which is made of iron with a zinc coating.
