This essay we would choose examples of insulators to talk about insulator knowledge, such as porcelain pin post insulator, which is one type of porcelain insulator, also called ceramic pin post insulator.

Porcelain pin post insulator structure:
Porcelain pin post insulator is made up of porcelain unit, iron cap, steel pin. The iron cap and steel pin are assembled with porcelain part with cement. The cap and pin should be on the same axial line and don’t have obvious deflection.

Porcelain pin post insulator design:
Porcelain pin post insulators are designed to two or more shell, to provide much higher voltage protection than any single insulator. As one of examples of insulators, porcelain pin post insulator is typically used on distribution power line. Porcelain is by far the most commonly used insulating material but there are a number of composite styles as well. Porcelain pin post insulators revolutionized the power distribution industry allowing much higher voltage protection -- there are several 36kV DC power lines utilizing pin post insulators.

About Porcelain pin post insulator/ceramic pin post insulator:
Available for any voltage and contamination level by changing number of insulators
Mechanical strength up to 12.5kN
High reliability through accumulated technology
Excellent long-term performance
