Transmission line post insulator is used to high voltage power line upto 132KV. And transmission line post insulator usually match with stud or bolts and mounted rigidly on supporting structure.

According to the material, transmission line post insulator can be divided into:
Porcelain transmission line post insulator
Polymer transmission line post insulator

For porcelain transmission line post insulator, there have different types as below:
Tie top line post insulator: ANSI 57-1, ANSI 57-2, ANSI 57-3, ANSI 57-4, ANSI 57-5
Clamp top line post insulator, vertical clamp mounting direction: ANSI 57-11, ANSI 57-12, ANSI 57-13, ANSI 57-14, ANSI 57-15
Clamp top line post insulator, horizontal clamp mounting direction: ANSI 57-21, ANSI 57-22, ANSI 57-23, ANSI 57-24, ANSI 57-25
Clamp top line post insulator, inclined horizontal clamp mounting direction: ANSI 57-31, ANSI 57-32, ANSI 57-33, ANSI 57-34, ANSI 57-35
