Porcelain Station Post Insulator

Porcelain Station Post Insulator widely used on transformer, distribution line, network and other electrical line. There are two general types for the insulators: normal type and anti-pollution type.

Porcelain Station Post Insulator details:
Solid-Core Station Post Insulators to meet ANSI C29.9 have the specific types as follows:
TR-202, TR-205, TR-208, TR-210, TR-214, TR-216, TR-286, TR-287, TR-288, TR-289, TR-291, TR-304, TR-312, TR-362, TR-369, TR391
Available color: grey, Brown
