IEC ANSI 57-3 Porcelain C-120 Line Post F Neck 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.
Specifications:
We produce Tie–Top Line Post Insulators, Horizontal & Vertical Clamp Top Line Post. Usually, the horizontal & vertical clamp top line post assemblies for ratings 25 kV through 35 kV. All Line Post Insulators are manufactured in strict compliance with ANSI standards , these insulators offer excellent mechanical strength as well as electrical characteristics.

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.
