The porcelain line post insualtor is for overhead line, mounting directly on the pole or tower. The most popular products are ANSI 57 series insulator, cantilevel strength range is from 3 to 13kN.

The vertical type line post insulator is similar to pin insulator design, with steel base and pin in bottom. The horizontal type has steel flange to fix on pole side and support conductor without crossarm.

The top part of insulator of both vertical and horizontal type can be integrated with 2 types of aluminum clamp depend on request.

The porcelain station post insulator is also called as solid core station insulator, used in the subsation, to support equipment such as PT, CT, surge arrester, and also to support conductor and busbar from the ground. According to system voltage, the station post insulator is designed by 1 or 2 or 3 sections, each section has one flange on both sides for connection.
