57 porcelain insulator is a type of ceramic post insulator in the power distribution line.
There are the following types:
Type 57-1/57-2/57-3/57-4/57-5/ 57-31/57-32/57-33/57-34/57-35/57-36
Porcelain Line Post Insulator are mounted to a supporting structure such as wooden/steel pole or tower through an additional base, used on overhead distribution and transmission from 10kV up to 138kV.
1- Tie Top type with Stud Base (Horizontal & Vertical Application):
Porcelain Line Post Insulators of ANSI 57-1, 57-2, 57-3, 57-4, 57-5, 57-6
2- Vertical Clamp-top type with Stud Base:
Porcelain Line Post Insulators of ANSI 57-11, 57-12, 57-13, 57-14, 57-15, 57-16
3- Horizontal Clamp-top type with Stud Base:
Porcelain Line Post Insulators of ANSI 57-21, 57-22, 57-23, 57-24, 57-25, 57-26
4- Horizontal Clamp-top type with Curved Base:
Porcelain Line Post Insulators of ANSI 57-31, 57-32, 57-33, 57-34, 57-35, 57-36
Power Line post porcelain insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events.
Horizontal and gain-based line post insulators are often used in applications to avoid the need to install a cross-arm on the pole.
We are one manufacturer of High Voltage Solid Core Station Post Porcelain Insulators and line Suspension ceramice insulators.
