ANSI Line post insulator 57-11,57-12,57-13,57-14,57-15
porcelain ANSI line post insulator ANSI 57-11,57-12, 57-13, 57-14, 57-15 definition:
The high voltage ANSI line insulator ANSI 57-11,57-12, 57-13, 57-14, 57-15 for over head line are produced according to the ANSI standard. what makes this different from the other types of ANSI line insulator, it is the top, ANSI 57-11 series have top with vertical mounting clamp.
ANSI line insulator 57-11,57-12, 57-13, 57-14, 57-15
Each type of porcelain line post insulator has the same characteristics, that is all made by porcelain and assembled with stud. The stud can be divided into long steel stud and short steel stud completed with nuts and washers. The long steel stud was used on wood cross arm, and the iron cross arm will be fitted with short steel stud.
Different insulator manufacturer has different design, but all are according to standard. For ANSI line insulator the code number on ANSI C29.7 is ANSI 57-11,57-12, 57-13, 57-14, 57-15. Brown and grey are two kinds of colors avalaible. Europe and United States mainly use grey color insulator.
In accordance with the cementing, we will use the high strength cement, poland cement to keep the high mechanical strength of Orient Power line post products for high voltage and medium voltage.
Solid core insulator can be described to ANSI line post insulator 57-11,57-12, 57-13, 57-14, 57-15, which is unpuncture type. The line post insulator can be performed safely on the over head transmission line and distribution line.
