Light gray Color Line Post Porcelain Insulator For Distribution
Lines F Neck
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:
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.
