Porcelain Station Post Insulator
Details
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.
