The ANSI 57-13 porcelain line post insulator provided by Orient is designed and manufactured with both economy and the installer in mind. The vertical line post insulator can be installed quickly and conveniently. The ceramic line post insulator specifications and photos are as follows.
The insulator’s exterior is coated in a high-quality glaze, making sure to shed water and keep dirt and other pollutants from adhering. This allows for a requirement of little-to-no maintenance. Any metal used in the manufacture of the post will not corrode or deteriorate. ANSI 57-13 porcelain line post insulator is composed into a shape that allows the wire and its physical support to be separated, while securing the conductor to itself.
