Oem Line Post Insulators ANSI 57-3 Porcelain C-120 Line Post
Insulator
Description:
Line post porcelain insulators shall conform in all respects to the
requirements of ANSI standard.
The insulators shall be made of good commercial-grade wet-process porcelain.
The entire surface of the insulator, with the exception of a firing surface, shall be glazed.
If gray is required, it shall be in accordance with ANSI Z55.1-1967 (R1973).
Metal parts shall be made of a good commercial grade of malleable iron, ductile iron, steel, or aluminum.
Ferrous parts, other than stainless steel, shall be galvanized in
accordance with ASTM A153.

Applications:
ANSI 57-2S Line post insulators are designed to provide rigid
support of conducting cable while offering the maximum resistance
to damage from electrical or mechanical events. Horizontal and gain-base line post insulators are often used in
applications to avoid the need to install a cross-arm on the pole.
Features:
Our porcelain insulators are manufactured using a wet porcelain
process and cured in an environmentally controlled production
facility to ensure a complete and even cure of the porcelain while
also resulting in the highest quality surface finish.
