Among the electrical insulators used in overhead lines, porcelain insulators still occupy 1/3 share. It often appears in the operation of the defective fault including zero value, broken string, rust, etc. Once the above problems occur will seriously affect the line safety, today to talk about the causes of the above problems and countermeasures.

What are the Classifications of Insulators? Which One is Better?
Power line insulators mainly have the following types: suspension insulators, pillar insulators, porcelain insulators, glass insulators, composite insulators, low-voltage insulators and high-voltage insulators, fouling-resistant insulators, and DC insulators.
