ANSI 57-2S Professional F Neck 12.5kN Line Post Porcelain Insulators
 
 
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.
 
 
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.
