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
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.
We offer a wide range of porcelain station post insulators. These products have demonstrated reliable performance in various types of applications all over the world.
Porcelain insulators are the traditional choice for distribution and transmission lines, busbar, and apparatus insulation. Manufactured from high-quality non-porous electrical porcelain, they provide long-life and cost-effective solutions for a majority of applications.
