ANSI 57-22 porcelain line post insulator is a kind of clamp top horizontal line post insulator with stud. This type distribution line post insulators has higher cantilever strength and bending strength for its horizontal application.

ANSI 57-22 porcelain line post insulator critical impulse flashover tests-positive:
Three line post insulators shall be selected at random for the critical impulse flashover test, positive, and tested in accordance with 4.7 of ANSI C29.1. Failure of the average critical impulse flashover value of the three distribution line post insulators to equal or exceed 92% of the rated critical impulse flashover value, as given in table 1, shall constitute failure to meet the requirements of this standard.

ANSI 57-22 porcelain line post insulator parameters:

ANSI 57-22 porcelain line post insulator is horizontal clamp top-cup base type porcelain line post insulator. Our distribution line post insulators from the latest high performance ceramics have been in use for many decades. We have experience with the manufacture of porcelain insulators. Research and further development resulted in the optimization of our line post type insulators for distribution plants and transmission systems.

In accordance with the standards IEC, ANSI, CSA and other certifications we manufacture single-component ANSI 57-22 porcelain line post insulator with high quality. More details about distribution line post insulators please contact Orient.
