What is porcelain post insulator?

Porcelain post insulator also named station post insulator or ceramic post insulator. Station Post Insulators are used for a variety of applications including supports for bus bar, fuse mounting, switch parts and other electrical devices.

We can produce station post insulators by two motheds idiostatic and wet-process. Idiostatic use for high voltage class. Most types porcelain insulators just like porcelain disc insulators, pin insulators, line post insulators etc, all thest types insulator made by wet-process.

Station post insulators have ANSI standard and IEC standard. And for the color, normally using of brown color and grey color.

IEC standard and ANSI standard types:
