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.

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.
