ANSI 57-12 porcelain line post insulator,vertical line post insulator

As vertical line post insulator, ANSI 57-12 porcelain line post insulator are now widely used to improve the appearance as well as performance of all distribution overhead, rural and urban.

Orient vertical line post insulator products are available for vertical mounting on wood, steel or concrete poles and steel structures. Stud mounted base is recommended for mounting on pole gains, brackets towers or structures. This type porcelain line post insulator is manufactured and tested to the requirements of current ANSI standards.

With various configuration options for the live end and ground end hardware fitting designs for different voltage levels are also possible for our line post insulators and ANSI 57-12 porcelain line post insulator is one kind of them. They provide years of service in the most unforgiving environments, such as extreme cold and heat, seismically active areas and corrosive situations such as seaside and petrochemical facilities.

The porcelain line post insulators range of our transmission and distribution line insulators includes products for vertical and horizontal installation. Orient has experience in the manufacture of these ANSI 57-12 porcelain line post insulator. The subsequent tests in the test labs guarantee for our customers first class products for lasting functionality and operational safety.
