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.
