22KV porcelain pin post insulator has high quality and god performance manufactured by Orient Power in China.

The reliability of 22KV porcelain pin post insulator depends upon its electrical and mechanical strengths. With the advent of modern manufacturing, mechanical molding and fixture technique, the mechanical strength is quite reliable.

Orient Power has about 30 years rich experience for porcelain insulators with most recent version about 23 years ago. Orient Power porcelain pin post insulators have better pollution performance and low associated costs.

Experience of outdoor insulation started from the introduction of telegraphic lines. The 22KV porcelain pin post insulators have been used since the last quarter of the 18th century. Porcelain insulators were the only type available before the introduction of newer polymer insulators.
