ANSI 57-26 porcelain line post insulator is horizontal clamp top-cup base type, and ANSI 57-21, ANSI 57-22, ANSI 57-23, ANSI 57-24, ANSI 57-25 together referred to as clamp-top line post insulator.
ANSI 57-25 porcelain line post insulator can be mounted horizontal on the steel crossarms or wooden poles as a good quality horizontal line post insulator for its super properties of porcelain insulating material.
ANSI 57-24 porcelain line post insulator is used in electrical system to prevent unwanted flow of current to the earth from its supporting points, and ansi standard line post insulator is the same with its application.
As horizontal line post insulator, ANSI 57-23 porcelain line post insulator is mainly exposed to pressure, bending and torsional forces during operation and have been specifically designed for this purpose.
ANSI 57-22 porcelain line post insulator is a kind of distribution line post insulators with stud. This type insulator has higher cantilever strength and bending strength for its horizontal application.
ANSI 57-21 porcelain line post insulator must be mounted as horizontal way and used for high voltage transmission and distribution line application, so it also called horizontal line post insulator 57-21.
Orient is an international line post insulator manufacturer and supplier of high quality porcelain line post insulators and porcelain pin post insulator.
