Product Description
ANSI 57-1 porcelain line post insulators
Xinghai insulator manufactures a complete line of wet process porcelain line post insulators for application through 88 kV. All insulators are solid core wet process porcelain and are manufactured and tested in conformance with ANSI Standard C29.7. Line post insulators are presented here divided into four separate groups-tie top designs, and clamp top designs of vertical, horizontal stud mount and horizontal gain base application. All insulator hardware (clamp yokes and bases) is ferrous. Standard color is sky gray, with chocolate available upon request.
