Orient-ANSI class 57-2 porcelain line post insulator

ANSI class 57-2 porcelain line post insulator is used on distribution line and transmission line upto 55KV. Tie-top line post insulator is mounted rigidly on supporting structure by means of a short or long stud.

ANSI C29.7 standard covers high-voltage line-post-type insulators made of wet-process porcelain and used in the transmission and distribution of electrical energy. ANSI class 57-2 porcelain line post insulator is mounted rigidly on supporting structure by means of a steed or bolts.
