Ceramic line post insulators are one special type insulator, Ceramic line post insulators are kind insulators which are solid core wet process porcelain and are manufactured and tested in conformance with ANSI Standard C29.7.
The main function of Ceramic line post insulators is support and fixed wire to keep a distance between conductor and earth, line post insulator ngk also prevent electrical current back to the earth.
